Biodiversity inventory on the Miguel Hidalgo reservoir for the AFD, El Fuerte, Sinaloa, Mexico

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 279 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage

The geographic scope of these inventories corresponds to the ecologically relevant area for terrestrial and aquatic organisms, considering the project's potential residual impacts. This includes the El Fuerte watershed and its tributaries from the second dam above the Manuel Hidalgo reservoir to its marine outlet, as well as all terrestrial habitats within a 500m buffer around proposed power line routes connecting the plant to Los Mochis.

Sampling Methods

FISH SURVEY
Sites were defined based on habitat parameters for the species (substrate, current, morphology) and the comparability between potential compensation sites and the project site. Different facies were evaluated when possible. For fish inventories, equipment was categorized into two groups based on usage:
Passive capture equipment:
- These devices were placed in water and left for up to 3 hours during the day or overnight for nocturnal species. Traps and baited pots were used, placed at various depths and substrates. At night, meat bait targeted Ictaluridae fish specifically.
- Active catching equipment: This gear was used by anglers in shallow areas, particularly on sandy, muddy, gravel, or small pebble substrates with minimal obstacles.
Local commercial fishing activity was noted. When time permitted, the consultant also:
- Analyzed local fishermen's catches (if available), documenting them with photographs.
- Conducted interviews with fishermen, identifying catches using photographic charts.

BIRD SURVEY
Bird data were collected using 20 m x 500 m strip transects through two methods:
- Observation points: Four observation points, spaced 150 m apart, were established starting at meter 25 of each transect. Observations, conducted over 12 minutes per point, recorded all birds within a set radius. These occurred early in the day under favorable weather conditions.
- Recording points: Acoustic sensors were placed at one point per transect, provided security conditions allowed. The system recorded bird sounds, which were analyzed using software, either manually or by comparison with pre-existing files. Precautions minimized sound contamination to reduce identification errors.
Habitat assessments focused on areas with natural vegetation (e.g., low deciduous forest, riparian vegetation) and modified habitats critical to local avifauna. Bird observation protocols included active listening, playback, and sighting with 12-minute intervals. Special attention was given to raptors due to their collision risk with power lines.

PLANT SURVEY
Sampling Sites : Representative sampling areas included locations for photovoltaic panel installations and the proposed power line route. Systematic area transects were selected for coverage. Sampling Methodology: Flora data were collected from 500 m² units (250 m x 2 m transects).
- Trees (diameter ≥ 7.5 cm) were recorded.
- Shrubs (diameter < 7.5 cm or insufficient height for diameter measurement), agavoids, and cacti were recorded in a 100 m² subplot.
- Herbaceous elements were recorded by cover percentage in a 1 m² quadrat.
The dry season complicated vegetation sampling, and future inventories should ensure data collection across seasons to capture species variability.
Data Analysis: Collected data were analyzed to identify plant species, assess species richness and diversity, and evaluate viable habitats within the project's

Method step description:

1. The mission aims to identify, characterize and verify the different types of habitats present in the area, previously mapped with geographic information systems. In addition to confirming and collecting as much quantitative data as possible on the presence of certain endangered species, susceptible to activate the designation of critical habitat.
