The forest regeneration works in the Sierra de Moratalla facilitate resilience and diversity of plant and fauna (16/10/2011)

Forest regeneration projects developed by the Ministry of the Presidency in the mountains of Moratalla, natural area that was affected by large-scale fire in 1994, have led to the recovery of species diversity and abundance, and colonization of the fauna.

The presidential advisor, Manuel Campos, stressed the "positive impact of forest management in this area, which has focused for several years to increase biodiversity, increasing forest area, improving living conditions and enhance wildlife protection against fire. "

The actions and silvicultural treatments carried out by DG Environment in the fire-affected areas have included thinning and regeneration of vegetation, which has respected the breeding period of species that could be susceptible to disturbances for this work.

This work has enabled us to strengthen biodiversity in the burned area, which has tripled the number of species between the untreated areas and those receiving silvicultural treatments a year earlier.

These are unique in that they are composed mainly of Aleppo pine mats, whose density prevents access of technicians to the area, and in them is less than the abundance and diversity of birds.

This is determined by a study conducted by the Ministry of Presidency, which analyzes and identifies bird species that have colonized the areas affected by the fire, the state of development and maturity of these populations, while comparing the diversity and density of species areas that have received treatment and post-fire that has not worked.

The faunal density difference on average between areas not worked and treated areas in 2009, is four times higher.

Over the years, maintaining a high abundance and species diversity, which in less favorable cases, are nearly double that of untreated areas.

The recovery of the forest is greater in areas with water availability and accumulation of flows, such as ravines, creeks and streams, which in turn have greater biodiversity bird.

These areas with pine islands, which burned in the great forest fire, are a special haven for wildlife, especially if there is little vegetation around, and they are also potential breeding areas for certain species of forest raptors .

In areas where there have been silvicultural treatments have been recorded from 45 species of birds.

Most are associated with open spaces and low shrubs, such as the partridge, the Crested Lark and Montesinos, warblers and finches, while the islands are isolated pine forest own copies, as the robin, wood pigeon and birthed .

By contrast, in ravines and streams converge all these species, which shows the importance of conservation.

Silvicultural treatments also increased the density of species such as rabbits, partridges and copies prey trophic position on a scale higher.

For example, the Sierra del Cerezo was colonized in 2010 by a pair of golden eagles.

Important forest enclave

Moratalla has a half-saw high mountains, steep and rugged, steep slopes, which dominates the Aleppo pinewood and tree species, with patches of scrub, esparto and rainfed crops.

The Sierra de Moratalla is an important location from the standpoint of forestry and wildlife protection, declared a Special Protection Area for Birds (SPA), a stronghold of forest areas which originally occupied the area.
