Key Biodiversity Areas in Guinea
We synthesized and analyzed fine-scale distributional data for 72 globally threatened species across 6 taxonomic groups and identified a total of 28 Key Biodiversity Areas covering 14,748 km2.
With geographic information gained on these sites, we've set the first Guinean Key Biodiversity Areas map.
Unfortunately accurate boundaries of most of these KBAs have not been assessed recently. As the second step of our conservation action, we'd like to demonstrate to decision-makers, using GIS tools, how severe the habitat loss is for threatened species by comparing two periods of time. This work could also help in planning conservation actions within these sites.
Priority Areas Identification for Conservation Actions in the South of Ecuador
Conservation of “Paratilapia Polleni” or sp.Marakely
A lot of dangers menace this species: degradation of habitat and aquatic ecosystem due to deforestation, erosion, hydrologic regime change, overexploitation of aquatic resources, and invasion of exotic concurrent and predatory species. Also, the people fail to recognize the Malagasy aquatic heritage because of lack of information and communications between different actors concerned with the endemic type of Malagasy aquatic species.
In face of dangers to this fish species, our association just carried out many concrete actions:
- IEC having as principal objective the sensitization of all responsible actors: decision-makers, economic operators, authorities, local communities
Because their ponds are far from the main road, they are required to rent carts at high costs or sell products at very low prices to the local retailers who dry fish. These retailers sell the fish at high prices five or six months later.
The objective of this project is mainly the reproduction and the conservation of the species which is seriously menaced. Consequently, our association works with many technical partners like Ministry of forests and environment, local authorities and fish breeders. The marketing of products will be planned in 2008. At least, the fish breeders will preserve the fish species and will benefit from fish sale. They would easily produce eight hundred kilogrammes every quarter and this operation would be able to earn about $2,400. Financially, this is of course very rewarding. However, these profits would not be regular owing to thieves who steal at night, vandalism acts, and variations in market demand.
All the same, the objectives of this group of "Paratilapia breeders" are to:
- increase number of fish ponds for conservation and multiplication of the species
In the end, conservation of this endemic fish needs a lot of care because this species only exists in Madagascar and intensive fishing may wipe it out. The fish producers always need permanent technical assistance from specialists for reproduction in order to preserve the species.
Our project will be presented with ArcGIS 8.3 with help from SCGIS-Madagascar
GIS tools for Land Use and Open Space Conservation 10:15 - 11:30
In 2004, the VHC sponsored a Master’s Group Project with the Donald Bren School of Environmental Science and Management (Bren) at the University of California, Santa Barbara (UCSB). The project developed a system using GIS spatial analyst to assist the VHC in prioritizing parcels of land within an 18,600-acre area of the Ventura hillsides for acquisition. In 2005, VHC in coordination with their consultants Rincon Consultants and Greenwood and Associates and supported by a $200,000 California Coastal Conservancy grant, expanded and fine-tuned the analysis to cover a 66,000-acre “Interest Area” centered around the open space areas north of the City of Ventura.
To analyze the conservation values of the Interest Area (IA), the GIS-based model scored individual parcels based on their cumulative resource values. The resource values (rubrics) evaluated for each parcel include Biological, Visual, and Recreation Resources. Each rubric was broken down into the following associated criteria as follows:
Biological Resources: Habitat Rarity, Documented Presence of Sensitive Species, Sensitive Species Habitat, Wetland Abundance/Value, Development Threat, Habitat Contiguity, Wildlife Corridor, Restoration Cost
Recreation: Public Access, Habitat Diversity, Grade Variability, Cultural Resources, Trail Connectivity, Scenic Resources
Aesthetics: Disturbance, Positive Features, View Contiguity
For each parcel, a score was identified for each criterion within a rubric. Scores ranged from (1) to (4), with (4) having the highest resource quality and (1) having the lowest. The average of all criteria scores within a rubric provided a total rubric score. Each rubric total score was weighted to balance the relative importance of each to the VHC.
The scoring system was applied to the expanded IA by revising individual criteria and their associated data layers, in order to reflect the expanded IA boundaries and newly collected data since the original UCSB study. Additionally, the analysis was modified to incorporate consideration for cultural, historical, hydrological, and geological resources, as well as development threat potential. In addition to the Criteria Scoring System analysis, technical studies of cultural, historical, hydrological, and geological resources and development potential and discussions with local experts and resource agencies were used to further refine the analysis of parcels suitable for acquisition.
The result of the model analysis revealed several key areas of high quality resources and allowed the VHC to hone in on key areas for property acquisition. This is important as all non-profits have limited time and resources. The GIS analysis and supporting technical studies have given VHC the tools to focus their efforts in contacting property owners, developing positive relationships, and applying limited funding sources towards property acquisition and management. The GIS analysis is intended to be a ”living document” that can be updated as acquisitions are made and conditions change.
Difficulties faced in Mapping Work to secure Traditional Land Rights from Industrial Development in Papua New Guinea (Managalas Experience).
Boundary mapping of the area had already started but had not progressed after 4 years because of many factors such as rough terrain, lack of GIS skills, conflicts between the locals, etc.
The Organization had attended a training conducted by the Centre for Training in Agriculture and Rural Development (CTA) in Fiji in March/April 2005 on participatory
Our wish for the future is that once the plateau is secured from destructive development processes, then we hope to use GIS and fill the details and generate maps of the plateau.
The 3D Model and GIS approaches and technique became an accepted practice by the governments in the Pacific region for conservation, resource planning, management and utilization and other uses.
Continued sharing of experiences and networking with practitioners and partners in participatory approaches internationally can assist us in our work of conservation, community development and especially poverty alleviation for our beloved people who live in rural areas that we work in.
Conservation Covenants in TLC: a ten year retrospective
Steps in the covenant process include landowner application, TLC review, possible survey and appraisal, baseline documentation, covenant document drafting and finally legal registration. From here, the covenant is monitored annually. The covenants that TLC hold range from large tracts of undeveloped land to small protected areas surrounding a residential use area (known as "development covenants"). Ecosystems protected include wetlands, grasslands, old growth forest, Garry Oak meadows and many, many more. Protection by covenant is effective because it protects land that might otherwise be developed at a lower cost, but covenants also carry challenges.
One challenge includes keeping on top of our annual monitoring obligations. The annual covenant monitoring visit usually includes a visit with the landowner, a check on the ecological state of the covenant area and a determination as to whether the covenant restrictions have been met by the landowner. Sometimes a violation will be discovered on a monitoring visit. Ideally, the violation will be georeferenced using a GPS unit and metes and bounds from a nearby survey point. To date, this has not been done with a GPS or GIS geo-referencing capability, but this would be ideal as we move toward best practice.
Solutions to these and other challenges may be sought by researching the history of covenants or easements in the U.S. and other parts of Canada where there is a longer history for this type of land protection. TLC is committed to improving our existing covenant management and ensuring new covenants we acquire protect land for generations to come.
