Participatory strategy carried out with environmental, tourism, surveillance and tourism service providers, academics and researchers and civil organizations, which sets the actions and goals to be achieved for the conservation of the reproduction, births and breeding of the sea lion colony as the most precious conservation object of the protected area and the most important source of income for tourism service providers.

In addition to the formality and territorial planning related to the Local System of Protected Areas, the municipality, based on environmental management, developed the following components as a highly important strategy:

- Promotion of incentives for community and landowner participation to restore natural protective vegetation that improves ecological connectivity and functionality.

- Awareness-raising and education actions to promote knowledge of the biodiversity of municipal ecosystems and the importance of SILAPE as a strategy to conserve this functionality and strategic ecosystems.

- Identifying the biodiversity of the different groups as fundamental knowledge to take actions for their conservation and encourage participation in conservation and conservation decisions in land use planning.

- Actions to protect endangered fauna in sites of connectivity disruption and vulnerability of highly important fauna species. Includes implementation of aerial wildlife crossings (61 installed).

The Municipal Council of Envigado adopted Agreement 009 which aims to contribute to the identification, conservation, management and proper management of strategic ecosystems and protected areas in the jurisdiction of the municipality, articulating these actions to departmental, regional and national management scales that strengthen human sustainability through the effective achievement of conservation objectives.

Protected areas in the urban context become an environmental determinant of land use planning and management, which, as higher-ranking norms, shield these spaces from changes that may be considered in relation to land uses other than the conservation and preservation of biodiversity and depend on political will for their management.

The relationship between stakeholders (institutional, citizen, academic, and private sector) allows the creation of administration and co-management mechanisms that respond to the needs of the protected area and the effective management within the framework of the execution of the Management Plans contributes to the environmental governance of the protected areas.

The guarantee of conservation of urban protected areas, beyond the technical and legal exercise of declaring them, is a robust process of social involvement. To this end, it has been essential to develop actions and strategies to promote recreation and environmental education around protected areas, expanding a collective awareness of the importance of their conservation, not only for biodiversity but also for the quality of life in the city.
The appropriation of socio-ecological concepts becomes a key factor in achieving the conservation objectives of protected areas. To the extent that stakeholders are committed to and recognize the values and ecosystem services that these types of spaces provide for the sustainable development of cities, the permanence of these spaces over time is guaranteed in desirable conditions for the conservation of biodiversity and amenity, enjoyment, well-being, and physical and mental health for all.

The objective of the intervention was to develop strategic planning to guide local investments for ecosystem and landscape restoration in an effective and efficient manner. In order to achieve this objective, a methodological framework was developed that includes four steps: 1) Mapping of relevant local actors at the territorial level, 2) Participatory analysis of the dynamics of environmental degradation, 3) Definition of objectives, goals and restoration activity and 4) placement of resources.

The mapping of relevant local actors was carried out using the GIZ "Capacity Works" cooperation model; for the analysis of environmental degradation and the definition of objectives, the "Open Standards for Conservation Practice" methodology of Conservation Measures Partnerships - CMP was used.

Silvocafe is a restoration technique that seeks to make wood production viable in coffee plantations, through the incorporation and management of a density of trees -AVC- as "shade trees". The steps to execute it are:

1. Extraction of mature trees: with a census and georeferencing of trees with DBH>10 cm, an extraction is carried out using the following criteria: frequency per hectare, phytosanitary condition, tree shape, density by species of interest and distribution.
2. Replant damaged coffee plants and incorporate HCV trees: each extracted tree affects approximately 20 coffee plants, that is, 500 to 700 plants/ha, which means a replanting of plants/ha of 10%-15% after each intervention.
3. Establish an adequate shade density of trees of high commercial value: this requires a stock of between 40 to 60 HCV trees/ha; with a recommended spacing of 12x14 m.
4. Plan thinning for shade improvement: Higher shade density (50-70% cover, 50-30% light) is justified when the crop site has high ambient and soil temperatures, low ambient and soil relative humidity, greater exposure to sunlight, poor soil fertility and low altitude above sea level.

In Helinge’er County, Systematic Conservation Planning (SCP) was used to plan ecological restoration and protection for the county with consideration of climate change forecast. Firstly, demands of regional ecosystem service functions were determined according to the national ecological function zoning and ecological red lines. Secondly, to ensure the key ecosystem types in each ecological function plot can perform long-lasting and reliable ecological service functions, historic and current status of each ecological function plot was evaluated with literature reviews and field investigations (community surveys), and ecosystem trends were predicted under different climate change scenarios. Community outreach was crucial in understanding how the lived experience of farmers and herders compared to the scientific literature and helped build trust with communities.

Targets of the protection area target were set, and the degree of human influence in the area was considered. Finally, for the important ecological function areas the current ecosystem status was compared to the key ecosystem types that can continue to play their roles. If they were consistent, they were identified as protected areas. Inconsistencies resulted in restoration areas, and the target ecosystem type for restoration could then be determined.

The environment is a continuum that is not bound by political-administrative boundaries. Unilateral measures that a country can take to protect a shared resource are generally ineffective and the unregulated use of the resource usually ends in its overexploitation and destruction.

Based on this, biodiversity conservation in areas of high ecological value in border areas should be done on the basis of cooperation and understanding between countries. However, these areas, far from the centers of decision making, are often not a priority for foreign ministries.

In these cases, civil society organizations play an important role, since they can move and articulate with a freedom that governments at different levels do not have.

To be effective, the governance of transboundary protected areas, such as the Tri-national Biological Corridor, requires the involvement of all stakeholders: local, regional and national authorities, entrepreneurs and organized civil society.
