Données sur le projet

This dataset was part of a project to advance access to quality freshwater data and information in Uganda by harnessing capacity in data mobilization, data available through GBIF and engagements with data user institutions. The goal was to advance utility of the data in conservation decision making, advocacy, education and reporting on biodiversity. Limited capacity of users to develop biodiversity information from primary biodiversity data, coupled with some deficiencies in data available through GBIF, is a main barrier to data use. This project worked to improve the quality of the data the National Fisheries Resources Research Institute (NaFIRRI) published through GBIF and used all the data available to develop freshwater biodiversity information to guide conservation planning. The quality of the occurrences were improved by linking them with abundance data and coordinates. Then, using all data available in GBIF, the project developed information products tailored to conservation planning. The information was envisaged to have a direct entry point into policies and practices of Uganda’s agricultural sector. The sector had been identified by the National Environmental Management Authority (NEMA) through a national biodiversity information Political and Economic Analysis (PEA), as the biggest sector threatening biodiversity. The information products developed were tailored to the information needs of the sector as defined in the PEA.

Titre Advancing freshwater biodiversity data and information access, utility and relevance for conservation decision making in Uganda
Identifiant BID-AF2020-145-USE
Financement The project was funded by European Union through the Biodiversity Information for Development (BID) programme of the Global Biodiversity Information Facility (GBIF). Co-funding was available from the JRS Biodiversity Foundation, Royal Belgian Institute of Natural Sciences, and Government of Uganda
Description du domaine d'étude / de recherche The project was a national project, mobilizing data from all water bodies in Uganda
Description du design NaFIRRI implemented biodiversity informatics projects in the past but freshwater biodiversity data remained in less useful formats especially for aquatic invertebrates and algae. Data mobilization in this project involved identifying and digitizing all available data from existing soft and hard copy records. Taxa occurrences and associated abundance data where applicable, were mobilized and published. The goal was to fill the data gaps. Our data mobilization design was such that, data was mobilized by each of the broad freshwater taxa (zooplankton, macroinvertebrates, fish and algae). Data for each of the broad taxa where possible, was grouped by each of the major lake systems in Uganda.

Méthodes d'échantillonnage

A ponar grab with an open jaw area of 238 cm2 was used to take samples of benthic macroinvertebrates. One to three hauls were taken from each sampling point. When more than one haul was taken, they were mixed to form a composite sample. The bottom type at each point was described from the grabbed contents. This was captured as location remarks. Samples were concentrated and then placed in labeled sample bottles and preserved with 5% formalin solution. In the laboratory, each sample was rinsed with water and then placed on a white flat-bottomed tray. Macro-invertebrates were sorted, and individual taxa identified to the lowest possible taxonomic level using identification keys (Mandahl-Barth, 1954), Pennak, 1953), Merritt and Cummins, 1997, De Moor et al. 2003). All taxa were recorded, and individuals of each taxon enumerated to estimate their densities.

Etendue de l'étude The datasets present data for surveys conducted between 2002 and 2020.
Contrôle qualité The samples were immediately processed in the field and treated with formalin to keep the organisms of interest intact. To avoid loss of organisms during sample processing, nets with appropriate mesh sizes were used.

Description des étapes de la méthode:

  1. Collection of the macroinvertebrates In the field, sediment samples were collected using a ponar grab with an open jaw surface area of 238 cm2. At each site, three sediment samples were obtained. The three samples were mixed and concentrated to form one composite sample for each site. Preserving the samples The composite sample for each site was separately preserved in 5% formalin to maintain the organisms in good condition prior to analysis in the laboratory. Identification of macroinvertebrates In the laboratory, formalin was rinsed off from each sample and placed in white flat-bottomed trays. Using pairs of forceps, all benthic macro invertebrates were sorted from the sediment and the individual taxa identified to the lowest possible taxonomic level using appropriate identification keys and a dissecting binocular microscope at 4x 25 magnification.
