The long-term monitoring on plant cover of Doñana shrublands is part of a harmonised protocol for the Long-term Ecological Monitoring Program of Natural Resources and Processes targeting Terrestrial Vegetation. The general aim of this protocol is to monitor and assess the dynamics of the main dominant terrestrial and aquatic vegetation types of Doñana. For shrublands, percent cover is recorded annually starting from 2008 to the present (2022) by staff of the Monitoring Team by one sampling campaign per year during the flowering season (between March and May) in 21 permanent square plots (15x15m). Cover is measured using the line intercept method in 3 transects of 15 m length oriented from East to West and located at fixed points of 2.5, 7.5 and 12.5 metres at both sides of the plot. Using the line-intercept method, the coverage of each species is measured with a measuring tape, including the class age (adult or seedling) and the canopy status (green or dead). This method enables to calculate the percent cover for each species across the transect and for the whole plot, including data on class age and percent of dry and green canopy, additionally to the percent of bare soil, plant density, species richness and vascular plant diversity for every plot.Sampling Description
Study Extent
The study area is located in southwest Spain in the Guadalquivir Basin and covers Doñana Protected Area (542.51 km2). Climate is Mediterranean sub-humid with Atlantic coast influence deriving in wet mild winters and dry warm summers. The rainy season occurs between October and April, with a peak in December–January (average rainfall is about 550 mm). Four main ecosystems are monitored in the area: freshwater marshes, mobile sand dunes, Mediterranean shrublands and woodlands and Doñana shoreline of 30 km. This monitoring is carried out in 21 permanent plots on Mediterranean shrublands in the Doñana Biological Reserve and sampled once per year, between March and May.Sampling
The long-term monitoring of Doñana shrublands started in 2008 by setting 21 permanent plots across the Doñana Biological Reserve. Each plot is sampled during the one sampling campaign per year in the flowering season (between March and May) in 21 permanent square plots (15x15m). Cover is measured using the line intercept method in 3 transects of 15 m length oriented from East to West and located at fixed points of 2.5, 7.5 and 12.5 metres at both sides of the plot. Using the line-intercept method, the coverage of each species is measured with a measuring tape, including the class age (adult or seedling) and the canopy status (green or dead). This method enables to calculate the percent cover for each species across the transect and for the whole plot, including data on class age and percent of dry and green canopy, additionally to the percent of bare soil, plant density, species richness and vascular plant diversity for every plot.Quality Control
The protocol used has been supervised by ecological researchers and the data have been validated by the members who performed the transects.Method steps
- Along each plot there was three different transects of 15 metres, on which a measuring tape was extended. The three transects are distributed at fixed distances from the Eastern side of the plot, the first one at 2.5 metres from the NE corner, the second one at 7.5 and the last one at 12.5 metres. All the individuals intercepted by measuring tape are identified and tape distance of the initial and the final contact point recorded, in order to calculate the total cover in the transect per species. Ancillary data on age class (adult or seedling: plant height under 15 cm) and the canopy status (dry or green) is also recorded for each individual. Average plant height is recorded for every transect. Percent cover of each species is calculated per transect and per plot. Data is collected in the field using a CyberTracker programmed sequence and download as Excel or CSV files.
