Covering approximately 6942 km2, Lake Manyara Basin in the northern-Tanzania is home to charismatic and unique flora and fauna. The basin is a corridor for wildlife constantly moving to and from Tarangire, Burunge and Lake Manyara National Parks (Ngana et al., 2004). The basin is also a home to the most biodiverse aquatic ecosystems including Mto wa Mbu River, Simba River, Kirurumo River, Msasa River, Endabashi River, Lyambi River, Magara River, and Makuyuni River, Lake Burunge, Lake Manyara and several permanent and temporary wetlands. Given that Lake Manyara Basin is of high socio-ecological importance to the region; renowned for high species richness and endemism across multiple taxonomic groups (VPO, 2015). Therefore, access to reliable, and ready-to-use freshwater biodiversity data is vital to guide policy formulation and decision-making processes for sustainable utilization and management of the basin’s freshwater biodiversity. This dataset presents data on the occurrence of freshwater macroinvertebrates from 4 rivers (River Iyambi, River Rohu, River Mto wa Mbu, River Babati), 1 permanent canal named Kissangeji and 60 temporary wetlands in the Lake Manyara Basin in the northern-Tanzania. In total, the dataset covers the period between 2019 and 2021, and contains (864 records and 727 observed taxa genera). The mobilization and preparation of this dataset were funded by JRS Biodiversity Foundation through Global Biodiversity Information Facility (GBIF) and its Biodiversity Information for Development (BID).Sampling Description
Study Extent
The macroinvertebrates were observed from 4 rivers, 1 permanent canal and 60 temporary wetlands systems of the Lake Manyara Basin, northern TanzaniaSampling
Macroinvertebrates sampling was carried out three weeks after inundation of the wetlands during the wet seasons. Macroinvertebrates were collected in 60 temporary wetlands by sweeping a 250-µm mesh D-frame net in different pond habitats (i.e., vegetation and open water) with a distance of 1 m per sweep. The number of sweeps was proportionally distributed over all microhabitats with attention for pond margins and areas with submerged, floating, and emergent vegetation. Collected macroinvertebrates were preserved in 70% ethanol. In the laboratory, specimens were isolated and identified under a stereo microscope at 40X magnification. Macroinvertebrates were identified to genus level and where possible to species level following different identification keys.Quality Control
Following Darwin's core quick reference, we compiled all the macroinvertebrate data into Microsoft Excel spreadsheets in accordance with the Darwin-Core standard. Using the "species matching" tool on the GBIF website (https://www.gbif.org/tools/species-lookup), we checked the taxonomic nomenclature. We cleaned the data to make sure it adhered to Darwin Core standard. To find any missing data in our dataset, we used the data validator tool on the GBIF website (https://www.gbif.org/tools/data-validator). Open-source software is used to create the two tools.Method steps

Geographic Coverages
The Lake Manyara Basin extends from 3°5′ to 4°5′ S and from 35°51′ to 36°37′ East. It is located within the Babati and Mbulu districts in the Manyara region and Monduli and Karatu districts in the Arusha region; covering an area of about 6942 km2. The main source of water in the basin is through precipitation and run-off from the upper catchment. Eight rivers drain water into the Lake Manyara Basin, these include Mto wa Mbu, Simba, Kirurumo, Msasa, Endabashi, Lyambi, Magara, and Makuyuni: which are also used by the surrounding communities for irrigation farming and as a water source for cattles. The basin houses two lakes, Burunge, and Manyara, and ubiquitous temporary ponds which are a source of water for humans, domestic animals and wildlife. The basin is also a corridor for wildlife constantly moving to and from Tarangire, Burunge and Lake Manyara national parks (Ngana et al., 2004).
