Attributes / Functions

Processes which maintain the target

1.  Wet Limestone Forest

 

Biodiversity Level:

Ecological system

 

Spatial Scale:

Catadupa

      Western component of the Cockpit Country plateau (regional)

 

      Highest rainfall values of the Cockpit Country plateau occur in Catadupa (regional)

 

      Aquifer contributes to freshwater security for western Jamaica, notably Montego River, Great River, and Black River (regional)

 

      Climate change adaptations:  Catadupa likely to be a moisture refugium during prolonged drought cycles (national)

 

      Recognized Important Bird Area (IBA), ranked 5th for importance in Jamaica (national; international)

 

      Recognized Key Biodiversity Area (KBA):  at least 8 plant species with global range restricted to Catadupa; supports 1 of 3 remaining confirmed national range restricted breeding populations of Giant Swallowtail Butterfly (IUCN EN); supports populations of at least 9 endemic frog species recognized as endangered or threatened by IUCN (national; international)

 

      Western component of the Highest Biodiversity Priority Cockpit Country add-on in the National Ecological Gap Assessment Report (2009)

 

      With the exception of 8 scattered Forest Reserves which cover 16% of the area, Catadupas wet limestone forest does not have protected status, despite being globally recognized for its biodiversity and nationally recognized for its contributions to freshwater security

 

      Plant communities associated with topography (e.g., hilltop, cliff)

 

      Endemic plants of the Cockpit Country plateau

 

      Epiphytes:  tank bromeliads (and associated faunal communities) and orchids1

 

      Forest-dependent endemic butterflies, notably the very rare  Grais juncta (currently known only from Catadupa and Quickstep), Atlantea pantoni (Catadupa is the second largest of 3 remaining small breeding sites in Jamaica), and Protographium marcellinus (Cockpit Country plateau is a stronghold)

 

      Endemic land snails, including Pleurodonte catadupae, which is globally restricted to Catadupa

 

      Forest-dependent bird species, including Jamaican Blackbird2 (IUCN EN), Ring-tailed Pigeon (IUCN VU) and Black-billed & Yellow-billed Parrots3 (both IUCN VU)

 

      Endemic reptiles, including Jamaican Boa4 (IUCN VU)

 

      Tree-roosting bats, notably the endemic Jamaican Fig-eat Bat

 

 

 

      Water regulation:  terrestrial component of karst aquifer

 

      Climate regulation (e.g. evapo-transpiration; intercept / block sunlight; nuclei for raindrop formation; temperature)

 

      Gas regulation (CO2- O2 cycles; carbon sequestration)

 

      Habitat:  refugium for Jamaica-endemic species; sole global location for site-endemics)

 

      Forest patch size:  large area supports greater diversity of plants == maintains year-round populations of pollinators and seed dispersers

 

      Forest structure (Note:  historic logging, esp. for railway has affected forest structure but possibly not diversity)

 

      Connectivity to other habitats, for different stages of species life cycles (e.g., butterfly seasonal movements / migration to interior moist habitats to avoid seasonal drought conditions in coastal areas)

 

      Production functions:  pharmaceutical potential

 

      Information functions:  aesthetic,  recreation, cultural (e.g., many place names (Mt. Horeb, Niagara, Shuna) highlight the unique water features of the landscape)

 

      Natural regeneration through pollination and seed dispersal

 

      Natural disturbance regimes:  creation of gaps (either through natural mortality of mature trees or through storm damage) and subsequent  successional dynamics

 

      Absence of invasive alien plant species, which arrest natural regeneration dynamics

 

      Minimum viable population sizes of each plant species to ensure adequate genetic variability

 

      Presence of keystone species, such as Ficus spp. which produce fruit year-round

 

      Daily / nightly movements of pollinators, seed dispersers and insect-consuming fauna (e.g., forest-dependent bats)

 

      Seasonal migration of pollinators and seed dispersers, which may require the maintenance of forest corridors to different habitat types

 

      Large and contiguous size to maximize interior :: minimize edge ratio

 

      Natural moisture gradient

 

      Connectivity between terrestrial forest and subterranean components

 

 

Notes

:1Mulgrave community members report that orchid and wythes ["wiss"] collecting no longer occurs in southern Catadupa.

2Jamaican Blackbird (local name = Wild Pine Sergeant) depends upon healthy tank bromeliads for foraging.  It is also highly vulnerable to brood-parasitism by the Shiny Cowbird.  Maintenance of forest connectivity / preventing fragmentation and creation of edge habitat should provide adequate protection for the Jamaican Blackbird.

3Mulgrave community members report that parrot poaching is not a problem in southern Catadupa.

4Mulgrave community members note that Jamaican Boas have always been rare in southern Catadupa (NB, elevation may be too high for the thermal range of this species); however poaching does occur in Maroon Town, but the extent and effects on the population remain unknown.  The species may require elevation to Target if poaching is determined to be a threat.

      Terrestrial components include the Niagara River and upper reaches of the YS River

 

      Recharge area for freshwater supply of western Jamaica, including the Great River, Montego River, and Black River, the latter of which is designated as a Triple Priority Overlap of terrestrial, freshwater, and marine ecosystems in the National Ecological Gap Assessment Report (2009).

      High level of threat because of pollution (incl. inappropriate solid waste disposal in sinkholes), pesticides, sedimentation, and nutrient enrichment

      Subterranean aquatic biota (stygobites and stygophiles) – mostly invertebrates

 

      Above-ground spring and river freshwater communities, which depend upon the quantity and quality of water filtered through the Catadupa aquifer; this will include diadromous species, such as Macrobrachium shrimp and Anguilla eels,  which migrate between the sea and freshwater ecosystems

Guild

 

Spatial Scale:

Catadupa

Spatial Scale:

National

 

 

      Endemic to Jamaica

 

      Largest butterfly in the New World

 

      Listed by IUCN as Endangered

 

      Very specific microhabitat and larval food plant requirements may not be addressed by protecting the wet limestone forest

 

      Historically ( up to 1970s) occurred in Mulgrave but no longer seen there; cause of decline unknown but likely associated with conversion of habitat and isolation of forest patches :: potential to restore into its historic range and increase population size

      Other forest-dependent endemic butterflies, notably Grais juncta (currently known only from Catadupa) and Atlantea pantoni (Catadupa is the second largest of 3 small breeding sites in Jamaica), and Protographium marcellinus (Cockpit Country plateau is a stronghold)

 

 

      Cultural icon, both for Jamaica and the Western Hemisphere

      Hunted illegally; hunters claim they might misidentify it in-flight during bird shooting season

 

      Global range restricted to the Greater Antilles.  Once considered abundant and widespread, it has undergone considerable declines across all islands.  In Jamaica it has been considered scarce since as early as 1840 and is now considered rare and local1
