Identifying Priority Areas for Conservation Actions in the South of Ecuador Gioconda Remache B.
Introduction In the 1950s and 1960s, biological ecosystems were considered stable and predictable Researches related to Tropical Ecosystems Functioning determine nature is unstable and dynamic Conservation networks: capacity to maintain ecosystems processes capacity of resilience Identification of Priority Areas: tools to preserve and manage natural and disturbed areas
General Overview Identify Priority Areas: Indicators selection Ecological Analysis Pressures-Threatens Analysis Define the priority areas Nucleus Zones Identification
Study Area Southeast Ecuador 638, ha ,880 m 64% denso, and chaparro forest; 10% herbaceous and shrubby paramo; remaining is disturbed area 8ºC - 20ºC 71% of PNP is inside
Podocarpus National Park Unique protected area in the south of the country. Floristic composition different from Northern and Central Andes. Relevant importance of endemism and biodiversity: 4% species are endemic of Ecuador 23% are exclusively in this area Important Bird Area (IBA): 628 bird species One of the most important areas to preserve viable populations of Andean bears
Core Area Index Identifies internal areas that are not affected by external pressures
Area and density Identifies the extension and level of compaction of the patches
Remnant Vegetation Identifies natural remnant vegetation in each basin identified
Interspersion and Juxtaposition Index Identifies the level of adjacency to other classes
Shannon's Diversity Index Measure of diversity in community ecology, applied here to landscapes.
Shannon's Evenness Index Shows the evenness of the spatial distribution of the identified classes
Patch Cohesion Index Defines the measures of the physical connectedness of the corresponding patch type
Singularity Quantifies scenic beauty, diversity, and endemism
Ecological Analysis Ecological Integrity Max Min
Pressure and Threatens Analysis
Accessibility Determines the facility or difficulty to access to vulnerable zones
Mining Industry Evaluates the presence or absence of mining industry
Distance to towns Identifies the habitants influence in the study area
Pressures-Threatens Analysis Pressures /Threatens Max Min
Priority Areas Restoration Areas Recovery Areas Conservation Areas
Priority Areas Restoration Areas Recovery Areas Conservation Areas Aim: Reforestation and revegetation with native species that were extracted from the area. Restoration Areas Moderate integrity zones, high threats. Low integrity, with high, moderate, and low threats. It covers ,82 ha ,20 ha (91,05 %) are not in the category of protection.
Priority Areas Restoration Areas Recovery Areas Conservation Areas Aim: To take actions to recover or regenerate native vegetation. They surround high integrity zones, so they are buffer zones. Recovery Areas High integrity zones, with high and moderate threats. Moderate integrity, with low and moderate threats. It covers ,59 ha ,22 ha (70,54 %) are not in the category of protection.
Conservation Areas Very high integrity zones, with low, moderate and high threats. High integrity zones, low threats enclosed in very high and moderate integrity zones. Aim: To implement management, protection and/or preservation actions to maintain ecological integrity. Priority Areas Restoration Areas Recovery Areas Conservation Areas It covers ,35 ha ,55 ha (86,70 %) are not in the category of protection.
Nucleus Zones ,39 ha Good connectivity 50% nucleus zones are inside of PNP. Critical importance zones identified inside of the conservation areas. Their propose is to consolidate and strength conservation zones through short term decision proposals Nucleus Zones
Discussion Consider to maintain the viability of umbrella species (Andean bear). Socio-economic information is needed. High Integrity values are isolated. Nucleus zones will be considered for conservation actions.
