First sampling of invertebrates and soils in the livestock tracks of the Community of Madrid

During the month of July, in the different sections of livestock roads of the Community of Madrid that are part of the LIFE CAÑADAS, the first sampling campaigns for soil and soil invertebrates have been carried out.

The team of researchers of the UAM has carried out during the second half of July the first sampling aimed at determining the diversity of soil invertebrates, as well as the state of soil conservation in the sections of livestock tracks, selected during the diagnostic phase of the project, of the Network of livestock roads of the Community of Madrid.

These sections have been classified according to their state of conservation or degradation such as: reference plots, plots that have a 'embedded' vegetation and eroded plots.

The methodology used has been the placement of pitfall or fall traps, which allow sampling of the target communities: on the one hand, ants, and on the other, larger arthropods (spiders, beetles, grasshoppers...). The traps, buried at ground level and with a solution of alcohol and monoethylene glycol (which allows the captured specimens to be preserved), remained in the livestock pathways selected for one week, after which they were removed for further analysis and identification.

Simultaneously, samples of the first centimeters of soil and plant biomass were collected in each of the plot typologies, and will subsequently be subjected to an analysis of physical-chemical properties.
