• As only one point in each site was sampled the effects of within woodland turnover, particularly in the larger sites, would have been missed.

• There were several small woodland glades dominated by various grasses.

• Rather than being a slowly changing woodland landscape it has undergone revolutionary changes.

• At the same time, the area of forests and woodlands is shrinking with changes in land use.

• Seasonal variation of foraging niches in a guild of passerine birds in a cork-oak woodland.

• Significantly, this includes the almost complete felling of existing woodlands to create a shelter wood with as few as 20-40 stems per hectare.

• Vegetation varies from woodlands and grasslands to dry scrub areas.

• The great majority (78%) of the 58 species from savanna woodland were recorded only in this habitat type.

• In woodlands, nutrient cycling is steady but slow compared with the faster rate of cycling in cleared pastures.
