TESSA case studies

TESSA has been used across a number of sites worldwide and by a range of users including students, conservation practitioners, governments and collaborative researchers. These case studies provide a selection of examples of how TESSA has been applied to help new users understand the tool in more detail with guidance from real examples.

Quarry ​Curfs​

Quarry ​CurfsThe Quarry Curfs are located northeast of Maastricht, between Maastricht and Houthem in the Province of Limburg. Covering 41 ha the former limestone quarry is already restored and managed by Limburg Landschap as a nature reserve. Vegetation colonisation has occurred relatively quickly and the site now contains over several species of conservation interest, including the yellowbellied toad (Bombina variegata). This assessment was carried out as part of an Interreg-funded project, known as Restore, which developed a framework for restoring minerals sites (quarries) to provide benefits for biodiversity, local people and local economies.

Sierra de Bahoruco National Park is situated in south-western Dominican Republic.

The site has been identified as an Important Bird and Biodiversity Area (IBA), a Key Biodiversity Area (KBA), an Alliance for Zero Extinction Site (AZE) and a Specially Protected Areas and Wildlife Site (SPAW). The Park serves as a refuge for more than 40 globally threatened (and often endemic) species. The purpose of this study was to generate information about the benefits people in and around the Park receive from the ecosystem, and their value. Grupo Jaragua (BirdLife in the Dominican Republic) has a long history working for the conservation of the Park and will use these results to advocate for its protection by providing scientifically robust data for the government to recognize the value of conservation and to enable better management at Sierra de Bahoruco.  A summary of the study is available in Spanish here  Download the Case study: Sierra de Bahoruco 


Copal community forest, Cameroon - Patrick Mbosso, environmental resources management and social issue centre


This case study was carried out in the COPAL community forest, which is located in the centre region of Cameroon. The ecosystem services provided by the community forest were compared to the services that would be derived from an alternative state of cocoa plantations (1) under certification and (2) not certified since agriculture is the main source of income for local communities and is driving land use change. The study found that global climate regulation, water quality and the value of harvested wild goods were reduced in the cocoa plantations, demonstrating benefits both locally and globally from conserving forest habitat. Download the Case study:  COPAL Community Forest.docx


Yala Swamp Complex, Kenya

Yala wetland lies on the north-eastern shoreline of Lake Victoria in Kenya. It is an Important Bird and Biodiversity Area and supports the livelihoods of many people who directly or indirectly depend on the ecosystem services provided in this area such as global climate regulation, water-related services (such as flood control), harvested wild goods, cultivated goods, nature-based recreation, ceremonial and spiritual services, cultural and Indigenous Knowledge services. The TESSA study assessed the value of harvested wild goods and cultivated goods through surveys that were distributed in sixteen villages within the area of study. TESSA facilitated the engagement of a variety of organizations on the issues facing the swamp and the ecosystem services provided and the results from the assessment were shared with stakeholders in order to continue to support conservation actions in the swamp.  Download the Case study: Yala Swamp Complex.docx


Khe Nuoc Trong, Vietnam

Khe Nuoc Trong forms part of Truong Son IBA which is situated in the Annamese
Lowlands of Vietnam (an Endemic Bird Area), close to the international border with Laos. This forest biome is one of the most threatened in Vietnam and this part of the Annamese Lowlands represents an important remnant of relatively undisturbed forest of this type. This ecosystem services assessment formed part of a pre-feasibility study for securing sustainable financing for the forest based on the benefits it provides to people locally and globally. TESSA was used to assess how the benefits would differ depending on two future pathways – one based on improved conservation of the forest and one following business as usual with over-harvesting and unsustainable logging. Download the Case study:  Khe Nuoc Trong, Vietnam.docx


Natewa Tunuloa, Fiji

This study was part of a Darwin Initiative project to deliver sustainable forest management for Fiji’s people and wildlife. The application of TESSA was conducted at three forest sites, including Natewa Tunuloa, to identify and highlight ecological and socio-economic values of forests to encourage Fijian communities to take up sustainable forest management Download the Case study:  natewatunuloa_12.09.16.pdf
