201

The Impact of Red Data Books (2002-2012) on the Conservation of Freshwater Fishes in Colombia

The reevaluation of Red Lists may show if initial alarms about endangered species have encouraged actions and management plans directed towards their conservation

The tropical dry forest is in a critical state of fragmentation and deterioration in colombia. most areas are under anthropic pressures such as cattle raising, human-built infrastructure, and agriculture.

203

The Continental Fishery Resource in Colombia

An important part of fishery production obtained from areas of high provision depends on threatened species. The major pressures affecting fishery resources in these areas must therefore be controlled to ensure their sustainability

204

Changes in Paramo Land Covers

The expansion of anthropic activities has transformed great part of natural paramo land covers. this phenomenon has caused significant losses in terms of paramo diversity and the ecosystem services they provide.

205

Wetlands and Human Activities

24% of the identified wetland areas in the national territory are being used by anthropogenic activities that cause partial changes in their ecology

206

The Red List of Terrestrial Ecosystems in Colombia

The criteria developed by the IUCN to evaluate risk levels of terrestrial ecosystems have been applied in the country for the first time

207

Forests, Savannas, and Paramos
