Abstract: The Western Ghats are globally
recognized as a hotspot of rich, endemic, and threatened biodiversity. Within
this hotspot of biological diversity, there are islands of natural landscapes
that can be termed as ‘hot specks’. These hot specks require careful
prioritization and specific management strategies as they vary in objectives
and ownership. Conserving hot specks of biodiversity is of great relevance
because creating new protected areas with wildlife corridors between them has
become relatively impossible in the present context of intensive land-use
change in this rapidly developing region. Management strategies, however, must
be based on scientific assessment and using a set of prioritization criteria
for selecting the most appropriate forms of management. The conservation action
plan for the Western Ghats has become a controversial issue based on the
findings in the report submitted by the Western Ghats Expert Ecological Panel
and the High Level Work Group on Western Ghats. In the present context of rapidly
changing land-use patterns, economic development, forest fragmentation,
isolation of habitats, linear intrusion, neo-urbanization and industrial growth
are threats to the pristine nature of the ghats.
Thus, there is an urgent need to identify, prioritize and manage the smaller
fragments of biological importance within the larger ecologically sensitive
landscape. A prioritization model for different types of hot specks is
essential so that it can be easily replicated by training frontline forest staff,
community-based organizations, Biodiversity Management Committees, and
non-government organizations for implementing a strategy and action plans for
the sites by using the Biological Diversity Act, 2002. Support of the local
Biodiversity Management Committees and the State Biodiversity Board is
essential for the conservation management of these biodiversity-rich sites.
This study presents an innovative approach to prioritize areas outside the
formally notified boundaries of the national parks and wildlife sanctuaries to
assess the conservation value of hot specks of diversity through a rapid
biodiversity assessment tool. This can lead to a rational conservation strategy
that conservation planners and practitioners can use.
Keywords: Biological diversity, forts,

Introduction
Western Ghats – a global
biodiversity hotspot
The term ‘biodiversity hotspot’
was first introduced in the late 1980s by Norman Myers as ‘specific areas on
earth’s land surface harbouring disproportionately
large numbers of extant species’ (Reid 1998). At first, a list of 18
biodiversity hotspots was identified based on the richness of higher plant
species (Mittermeier et al. 1998). Later new areas were included, and the list
of biodiversity hotspots was increased to 25 (Fisher & Christopher 2007; Laurance 2007b). Currently, 35 global biodiversity hotspots
have been identified (Laurance 2007a; Williams et al.
2011).
The Western Ghats are one of the
first 18 globally identified biodiversity-rich hotspots. The mountain range is
believed to be older than the Himalayas and spreads across six western states
of India, in Gujarat, Maharashtra, Goa, Karnataka, Tamil Nadu, and Kerala (Kumara & Singh 2004; Pai
2005). Among these six states, Maharashtra is the most urbanized and
industrialized region making it vital to create a locale-specific viable
management strategy for this ecologically sensitive area (Mohan & Pant
1982; Ghatge et al. 2013).
Biodiversity conservation – a
significant concern
The impacts on the landscape of
the Ghats have initiated unsustainable patterns of land management in the
Western Ghats (Panayotou & Ashton 1992; Menon
& Bawa 1997). This has become a serious concern
for biodiversity conservation as new protected areas are not a feasible option
in the present context. The notified protected areas are being conserved
through the Wildlife Protection Act, 1972 and various rules and regulations.
These formally recognized protected areas were considered an adequate strategy
for conserving biodiversity two to three decades ago (Beresford & Phillips
2000). However, recent studies have shown that a large part of the floral and
faunal species diversity is present in the landscape elements outside the
protected area network (Bhagwat & Rutte 2006).
The current protected areas are thus insufficient for conserving the species
and ecosystems, which are critical biological assets at global, national and
local scales (Lindenmayer & Franklin 2002;
Bhagwat et al. 2005; Lindenmayer et al. 2006;
Shrestha et al. 2010).
Due to the current rapid growth
of urbanization, industrialization, mining, transportation facilities, and
infrastructure development, it is not feasible to notify new protected areas
under the Wildlife Protection Act, 1972 or extend the boundaries of the
existing protected areas, or create viable corridors between the protected
areas is also a contentious issue (Mathur & Sinha 2008). The existing
pressures are leading to a loss of species diversity in the protected areas and
potential forested corridors connecting them (Gardner et al. 2010). However,
there are several small and large landscape elements in the Western Ghats with
high species concentrations that are not confined within the boundaries of
existing protected areas in this ecologically sensitive area (Gadgil et al. 2011). The surrounding landscape elements of
the protected areas form a matrix of cultural landscape elements that are
permeable to several species such as small mammals, avifauna, amphibia,
reptiles and insect life. The specialized habitat fragments surrounded by
human-dominated land-use are representatives of small patches of natural or
semi-natural ecosystems of the Western Ghats (Anand et al. 2010). These
biodiversity-rich islands of forests are referred to as ‘hot specks’ (Cherian
1995). As defined, these hot specks are miniscule areas of species
concentration, varying in size from five to rarely a few hundreds
or more square meters falling within of far outside todays recognized hotspots
where species-packing of diverse groups, including many endemics is found
(Cherian 2000). They constitute a mix of varied elements that are effective as
a support system for biodiversity conservation and could constitute a second
line of reserves that act as biodiversity rich islands between the protected
areas for a variety of floral and faunal elements (Bharucha
2006a, b).
Need for identifying biodiversity
hot specks
A greater ecosystem is present in
the landscape matrix dominated by socio-ecological elements outside the
protected area boundaries. Conserving this large ecosystem is not a possible
solution considering the human dependency on these landscapes. There is a need
to identify key locations within this ecosystem for managing important
ecological functions (DeFries et al. 2007).
Identifying and conserving the biodiversity-rich ‘hot specks’ in a mosaic of
cultural landscapes has become a priority for developing a network of
biodiversity rich islands that will support the effective movement of wild
fauna between the protected areas, as creating continuous corridors between
protected areas is not a feasible option (Bhagwat et al. 2014; Trivedi et al.
2018). The increasing pressures on land use thus requires an innovative
strategy aimed at conserving these multiple biodiversity rich hot specks that
can act as areas that fauna can use to cross from one forest patch to another.
Hot specks of diversity nested between existing protected areas are essential
elements within the matrix of man-modified cultural landscapes.
Purpose of the study
The purpose of this study was to:
Identify the different important
landscape element typologies of hot specks present with the Western Ghats of
Maharashtra (Figure 1).
Prioritize each site within these
different landscape elements using a set of scientific assessment parameters
based on the evaluation of their biodiversity
and anthropogenic threats that
affect them adversely.
Suggest a unique management
strategy based on the prioritization of these hot specks.
This study can act as an up
scalable model for the rest of a large number of hot specks in the Western
Ghats.
Methods
Identification
of hot specks
A survey of
relevant literature provided a list of 14 possible hot speck typologies (Bharucha 2010; Trivedi & Bharucha
2019). Based on the available secondary data, sacred groves, forts, and
plateaus were selected for the survey as they are key areas easily demarcated
and can be managed (Naravane 1995; Deshmukh et al.
1998; Watve 2013). Hot specks under the three
typologies (sacred groves, forts and plateaus) were plotted on a study area map
and were selected for the ground survey through a purposive sampling technique.
Assessment
of the hot specks
The Rapid
Biodiversity Assessment Tool was developed consisting of important
parameters categorized into biodiversity and anthropogenic threats that were
further divided into several relevant subcategories (Figure 2). These
parameters included shape and size, structure of the forest and its condition,
presence of faunal diversity, special features, surrounding matrix (Hopkins
& Skellam 1954; Adams et al. 1998; Ranta et al. 1998; Vázquez-García & Givnish
1998; Plumptre 2000; Ricketts 2001; Hill et al. 2005;
Ormsby 2011; Trivedi et al. 2018). Anthropogenic
threats include various types of gradually increasing local livelihood threats
such as clearing natural landscapes for expanding agriculture and grazing,
forest fires, felling of trees and lopping branches and current modern threats
arising from the rapid sale of land, development of roads and transportation,
powerlines, mining, windmills, industries, neo-urbanization and tourism were
included as a part of the evaluation (Padhye et al.
2006; Davidar et al. 2007; Anitha
et al. 2009; Subramanian et al. 2011; Mehta & Kulkarni 2012; Trivedi et al.
2018). The assessment parameters were quantified using a score from 0 to 10 (0
– absent, 2.5 – poor/ low, 5 – fair/ moderate, 7.5 – good/ significant, and 10
– very good/ high) (Trivedi et al. 2018). This scoring system was developed
based on the assessment technique used for assessing the management
effectiveness evaluation (MEE) of tiger reserves in India (Mathur et al. 2011).
The rapid
biodiversity assessment tool (RBAT) is modified from the rapid assessment and
prioritization of protected area management (RAPPAM) technique developed for
WWF’s ‘Forest for Life’ programme (Ervin 2003a; Getzner et al. 2012). These tools were modified so that
they can be used by ground level practitioners such as forest department staff
and the local Biodiversity Management Committees under the provisions of the
Biological Diversity Act, 2002 (National Biodiversity Authority 2002).
A set of questions
was designed for conducting semi-structured interviews with the local people
(Longhurst 2003). The interview data is an essential part of the RBAT. It fills
the one-time temporal gaps from the survey and provides a time series over the
last couple of decades. Interviews can be done relatively quickly and provide
local insights that are not obvious in a biodiversity and vegetation-based site
analysis (Ervin 2003b). Thus, social issues and cryptic faunal values have
emerged through this exercise.
Developing
a geospatial database of the hotspecks
A
normalized difference vegetation index’ (NDVI) was processed using LANDSAT 8
satellite images for the entire study area. The technique was first used in the
early 1970s, and it uses visible and near-infrared bands of the electromagnetic
spectrum for identifying the presence of live vegetation on the ground (Sahebjalal & Dashtekian
2013). A buffer of 2 km2 was created around the hot specks surveyed
to study the peripheral vegetation cover. The GPS coordinates of hot specks
were documented during ground-truthing and were plotted for the Western Ghats
of Maharashtra using the ArcGIS platform.
Road
network was acquired from Open Street Map and overlaid on the study area to
identify the type of road connectivity to the hot specks. A buffer of 2 km2
was created around all the identified hot specks from the secondary database to
develop a network of hot specks forming a potential wildlife corridor. The
database of all the three hot speck typologies was linked with the hot speck
maps, and a geospatial database was developed to acquire additional information
on the hot specks (Kushwaha & Roy 2002).
A
prioritization matrix was developed consisting of 16 categories for
prioritizing the surveyed hot specks. These hot specks were then categorized in
the matrix based on the biodiversity and anthropogenic threat values obtained
from the field survey (Trivedi et al. 2018).
Developing management strategy
for hot specks in the Western Ghats
Notifying these biodiversity hot
specks as protected areas under the Wildlife Protection Act, 1972 can create
new conflict issues. However, the Biological Diversity Act, 2002 is a feasible
option since several local and tribal communities are dependent on these hot
specks for their livelihood, and local Biodiversity Management Committees are
empowered to legally take on this task (West & Brockington 2006). The
conservation of these areas requires an innovative approach through which
multi-stakeholder participation is incorporated into the management of the hot
specks (Miller 2005).
A detailed literature of
traditional, existing and new conservation approaches was reviewed for defining
possible management strategies. Several new approaches under the rules and
guidelines of the Convention on Biological Diversity and the Biological
Diversity Act, 2002 were identified and can be used for conserving the
prioritized hot specks based on the scores from assessment of biodiversity and
anthropogenic threats (Gadgil et al. 2011).
The conservation of these hot
specks requires active participation of various stakeholders. Government
departments, especially the Forest Department and the Maharashtra State
Biodiversity Board, as well as educational institutes and non-government
organizations, have a crucial role in building and strengthening the capacity
of the local communities and generating awareness for conserving these islands
of rich biodiversity (Singh & Rahman 2012).
The Companies Act, 2013 has
provided a potential pathway for corporates to initiate biodiversity
conservation through their Corporate Social Responsibility (Ministry of
Corporate Affairs 2013). Additional funding through corporates is an option for
supporting these programs (National Biodiversity Authority 2019).
Results
A sample size of 51 hot specks
(19 sacred groves, 15 forts and 17 plateaus) were identified for the ground
survey through purposive sampling from a total of 376 hot specks (Figure 3
& 4). The data collected from the ground survey and interviews were
assessed for their biodiversity and anthropogenic threat scores (Table 1). They
were depicted graphically and plotted in the prioritization matrix (Figure 5, 6
& 7; Table 2, 3 & 4). The combination of biodiversity and anthropogenic
threats show that one sacred grove, one fort and one plateau recorded high
biodiversity asset values. There is a significant negative correlation between
biodiversity and anthropogenic threat scores, indicating that as anthropogenic
threats increase, the value of biodiversity decreases (Table 5). Assessment of
threats indicated that there had been a loss of traditional knowledge practices
such as spiritual importance, agriculture and grazing while tourism,
transportation, and urbanization had a more significant role in degrading the
biodiversity of the hot specks and had spread across the surrounding matrix in
the landscape.
Geospatial analysis
The results of geospatial
analysis indicated that the scores of biodiversity and anthropogenic threats
could be closely linked to the road connectivity of the hot specks (Figure 8).
It provided an indicator of the overall anthropogenic threats that were
degrading the biodiversity values of the hot specks. The anthropogenic threats
showed that roads were linked to other threats as a cause- and- effect
phenomenon which has increased over time. The effect of one threat that led to
degrading the hot speck became a driving force for other threats. The analysis
of road network connectivity to the hot specks has indicated that a total
of nine hot specks (five sacred groves,
two forts and two plateaus) are connected with a national highway, seven hot
specks (two sacred groves, three forts and two plateaus) are connected with
state highway, two hot specks (two forts) are connected with major district
road, 32 hot specks (11 sacred groves, eight forts and 13 plateaus) are
connected with other district roads and one hot speck (one sacred grove) is
connected with a dust road. The road connectivity to a hot speck has led to
other threats causing degradation of the biodiversity in the hot specks.
Moderate to high anthropogenic threats have been recorded in four of the five hotspecks connected by national highways. The results
showed that 32 out of 51 hot specks were connected by other district roads,
which recorded moderate to high anthropogenic threats. A further analysis
indicated that the stretch of the other district roads connecting the 17 hot
specks were connected indirectly to either a national or state highway. In the
case of Korigad fort, Khingar,
Ambral, Dandeghar, Rajapuri, Mahabaleshwar 1, 2, & 3 plateaus, the hot
specks are connected by other district roads, which is further connected to
major district roads. The major district roads are in the near vicinity of
popular tourist destinations.
A key concern is the quality of
the surrounding matrix. A buffer of 2 km2 created for the hot specks
identified from the secondary database have resulted in a potential
intermittent functional wildlife corridor connecting protected areas from Kalsubai Wildlife Sanctuary in Maharashtra State to Mhadei Wildlife Sanctuary in Goa State (Figure 9).
Management of hot specks – a dire
need for conservation
The 51 hot specks (sacred groves,
forts and plateaus) surveyed in this study are present outside the boundaries
of the National Parks and Wildlife Sanctuaries. Hence, there are no stringent
rules and regulations protecting these biodiversity rich hot specks. As a
result, changes within the hot specks such as complete renovation or
development of deity temples in the sacred groves were observed which has led
to thinning of grove canopy and is attracting religious tourism (Image 1 &
2).
An important information recorded
from the local interviews was that the sacred groves are not conserved for
their biodiversity values but because of religious sentiments. However, the
local people are aware of the changing landscapes leading to biodiversity loss.
A growing demand of tourism for forts is leading to its beautification and
attracting development of roads, small and medium scale eateries, and parking
areas (Image 3,4).
These development processes are
impacting the areas within fortified walls as well as the fort hill slopes.
Unlike sacred groves and forts, plateaus are under pressure from tourism, roads
passing through them, mining, power generation projects and grazing, all
leading to loss of several seasonal endemic flora (Image 5).
Solid waste is a common threat
observed in all the hot specks (Image 6). Land use change in the surrounding
matrix is another anthropogenic threat found in hot specks that were connected
to state or district highways. There is a dire need to develop and implement a
sustainable management system for conserving these biodiversity hot specks
taking into consideration the livelihood needs of the local communities.
Discussion
The current study has highlighted
that there are several fragments of biodiversity-rich areas outside the
protected areas in the Western Ghats termed here as biodiversity hot specks which
can act as transit areas across permeable areas for wildlife movements between
protected areas (Das et al. 2006; Ray & Ramachandra 2010; Trivedi & Bharucha 2019). These hot specks ensures the genetic
viability of disjointed protected areas. There is currently sufficient evidence
that they harbour significant levels of biodiversity
and are used as transit areas for different species of wildlife (Trivedi et al.
2018). These identified hot specks have the potential to be developed as an
additional conservation network. The hot specks support the protected areas
system of National Parks and Wildlife Sanctuaries by forming multiple islands
of biodiversity in a matrix of cultural landscapes by providing permeability
for movement of wild faunal diversity (DeFries et al.
2007; Perfecto & Vandermeer 2008; Ormsby & Bhagwat 2010; Ray & Ramachandra 2010).
These hot specks of biodiversity are essential in a situation where developing
a continuous wildlife corridor is not possible due to the existing other
land-use patterns (Blicharska et al. 2013).
Urbanization, tourism, and windmill installation will place further stressors
on conservation values in the near future.
The ‘Rapid Biodiversity
Assessment Tool’ developed for this study is also referred to as Rapid Ecological
Assessment, or ‘Biorap’. This technique is used for
conducting assessments for various ecosystems such as terrestrial, marine and
freshwater where only a small amount of data or no information is available (Margules & Redhead 1995; Sayre et al. 1999; Patrick et
al. 2014; Trivedi et al. 2018). Currently, in the Western Ghats, there is only
a list of these hot specks with little if any geospatial or quality indicators
for prioritization. The RBAT has filled this gap with important information on
the prioritization of areas so that management can be developed on
locale-specific lines.
Participation of the local
communities plays a crucial role in conserving these biodiversity rich hot
specks. Under the Biological Diversity Act, 2002, the State Biodiversity Boards
have formed the Biodiversity Management Committees (Venkataraman 2009; Laladhas et al. 2023). The Biodiversity Management
Committees have developed Peoples Biodiversity Registers that contain
information on the availability and knowledge of local biological resources
present in the area (Gadgil et al. 2000). These
prioritized hot specks outside the protected areas can be declared Biodiversity
Heritage Sites under the Biological Diversity Act, 2002 or as Community
Reserves or Conservation Reserves under the Wildlife Protection Act, 1972
(Singh & Kushwaha 2008; Raghavan et al. 2016). The RBAT helps choose an
appropriate legal and administrative option.
Another approach for conservation
is designating the hot specks under ‘Other Effective (Area Based) Conservation
Measures’ developed by the International Union for Conservation of Nature
(Convention on Biological Diversity 2018). This is a strategy suggested in
Sustainable Development Goals, Aichi Targets and the National Biodiversity
Action Plan targets. Other stakeholders, such as corporates through their
Corporate Social Responsibility, can provide funds. Non-government
organizations, educational institutes and private landowners have an equally
important role in supporting the local communities for conserving the hot
specks (Kanagavel et al. 2013).
Conclusion
The Western Ghats is dotted with
thousands of biodiversity rich hot specks present in the natural and cultural
landscapes. The current study on ‘Identification, prioritization, and
management of hot specks in the Western Ghats of Maharashtra’ has identified
different typologies of biodiversity rich islands referred to as ‘hot specks’.
These are present in the socio-ecological landscape elements outside the
boundaries of national parks and wildlife sanctuaries.
The Rapid Biodiversity Assessment
Tool developed for evaluating the hot specks of biodiversity has proved to be
effective in assessing sacred groves, forts and plateaus. With necessary
modification, this assessment tool can be used for assessing a larger number of
hot specks under different typologies present in a greater ecosystem of
socio-ecological landscapes. This however requires a minimum necessary capacity
building of frontline forest staff, community-based organizations, Biodiversity
Management Committees, and non-government organizations for implementing the
assessment tool in the field. The prioritization of hot specks based on the
analysis of biodiversity and anthropogenic threat scores generated from RBAT
enables the land use planners to classify the sites in 16 categories. These 16
categories mentioned in the prioritization matrix enables the planners with a
freedom to identify priority categories and select hot specks that urgently
need to be brought under the hot specks conservation action and management
plan.
A multi-stakeholder management
approach should be developed for implementing the hot speck conservation action
and management plan under the National Biodiversity Action Plan. Under this
management approach, funds and resources should be allocated to the State
Biodiversity Board(s) which will be used by the frontline forest staff,
community-based organizations, Biodiversity Management Committees for
identifying and assessing hot specks and preparing peoples biodiversity hot
specks register (PBHR). Peoples biodiversity hot specks register will consist
of information on biodiversity and threat existing within and outside different
hot specks identified and surveyed in the socio-ecological landscapes for the
prioritization purpose. Once prioritized, these hot specks should then be
brought under the hot speck conservation action and management plan. This can
be achieved by notifying the prioritized hot specks as Biodiversity Heritage
Sites, Community Reserve, Conservation Reserves, or as Other Effective (area
based) Conservation Measures under the Wild Life (Protection) Act, 1972 and
Biological Diversity Act, 2002. Funds can then be allocated to the respective
Biodiversity Management Committee for the conservation and management of the
hot specks. The capacity building and training of frontline forest staff and
Biodiversity Management Committees will be an important part in this entire
process which can be done with the support of non-government organizations and
education institutes. A public-private partnerships could be established where
corporates and other sectors can put in their funds and resources for
conservation and management of these biodiversity hot specks.
