Tree species recorded in the cocoa landscape within the corridor area in the Western Region of Ghana.

Citation

Osei-Owusu Y, Owusu-Achiaw R (2018). Tree species recorded in the cocoa landscape within the corridor area in the Western Region of Ghana.. Conservation Alliance International. Checklist dataset https://doi.org/10.15468/1bezfp accessed via GBIF.org on 2023-03-29.

Description

This study is based on the premise that appropriate tree shade in cocoa systems promotes the longevity of cocoa production and enhances biodiversity conservation and carbon storage in agro-ecosystems. This can enhance poverty alleviation among cocoa farming households and biodiversity conservation while providing safe wildlife corridors and mitigating climate change effects It is believed that promoting high diversity shaded cocoa agroforests offers an opportunity for diversifying farmer income through diversified farm products and carbon trading. This provides an extra economic incentive to cocoa farming thereby protecting ecosystem health and improving agricultural sustainability.The study was carried out in ten (10) communities randomly selected from the communities within the range of the proposed Ankasa-Bia-Krokosua ecological corridor in the Western region of Ghana.

Purpose

The purpose of this dataset is make biodiversity information available to decision makers. The data was mobilized and published under the Africa Biodiversity Challenge 2018 coordinated by SANBI and funded by JRS Biodiversity Foundation.

Sampling Description

Study Extent

The data points were taken at the proposed Ankasa-Bia-Krokosua ecological corridor that were found between latitudes 7.906669 North and 5.317087 South and longitudes-3.006151 West and -1.854438 East. The sampling period was done once on May 05, 2013. Ten (10) communities/villages were randomly selected across the study site, and in each community, ten (10) cocoa farms were randomly selected for the tree diversity assessments.

Sampling

In this assessment, a sampling process was adopted for estimating native and exotic tree species diversity. The process involved the direct use of field measurements using sample plots in the assessment of tree populations, distribution, diversity, and other statistical estimates. Ten (10) communities/villages were randomly selected across the study site, and in each community, ten (10) cocoa farms were randomly selected for the tree diversity assessments. Locations of all selected farms, together with important landmarks were determined using the GPS coordinates for purposes of superimposing them on appropriate land use maps. In each cocoa farm, elementary plots of 50 m x 50 m (2,500 m2) were demarcated, resulting in a total of 100 plots and a total sampling area of 25 ha (initially the plan was to use plots of 25 m x 25 m for the assessment but after a quick reconnaissance on the field it was necessary to scale up the plot size). All individual plants associated with cocoa, with diameter at breast height (DBH) ≥ 10 cm were identified and recorded, and where identification on the field was not immediately possible specimens were collected and identified in the Herbarium at CSIR- FORIG. One key-informant per village was also interviewed to record main use of species (edible, medicinal, high value or low value timber amongst others).

Quality Control

Only tree species in cocoa farms were sampled and recorded. All measuring instruments were correctly calibrated. All recordings were made in uniform units. The sampling procedures were duly followed. All ten (10) sampled communities were randomly chosen within the Ankasa-Bia-Krokosua ecological corridor.

Method steps

  1. All data points were entered in excel worksheet using the Darwin Core standard template for Core Taxon (Checklist) data and cleaned from errors using the filter on the excel worksheet. All names were resolved and verified or validated using the Global Name Resolver . The taxonID for instance RMSC:FIP:CTD:0001 was created using the institution code (e.g. RMSC), the name of the project (FIP), the type of data recorded (CTD i.e. Cocoa Trees Data) and the sequence of the records (e.g 0001 for the first tree species species in cocoa farms recorded).
    The cleaned checklist datasets were then uploaded into the OpenRefine software for further cleaning and the cleaned dataset was then downloaded as text file and uploaded into the IPT for publishing by filling and completing all required metadata associated with the dataset Data for the purpose of the publication was darwin core formatted. Scientific names were crossed using the Global name resolver tool and verified using the GBIF backbone Taxonomy and Catalogue of Life. Further cleanings were also done using the OpenRefine.

Additional info

The study was to provide information on Cocoa agroforests as great potential for conservation of biodiversity, as they can create a forest-like habitat that harbours biodiversity, even in rapidly degrading landscapes, while providing economic and social benefits to small-holder farmers. In fragmented landscapes, they may also provide habitat and resources for animals and plants, while helping to maintain connectivity between forest patches. This combination of environmental, social and economic benefits from agroforests has led to their promotion as a ‘win-win’ land use system for Ghana and Africa as a whole.
