Woodland Project Phase 2 Survey Report



Seedlings occurred in surprisingly high densities across most of the project site, given that clearance has only just been completed (Figure 7).

Figure 7. Seedling Density - Survey 2


The largest number of seedlings was found in Square 3, which is also somewhat surprising (Figure 7). The region represented by Square 3 has been cleared for several years now and it might be assumed that the seed bank would by now be somewhat depleted in comparison to the other areas still covered in Rhododendron. Raking off the leaf litter once more is likely to have been beneficial in that seeds long buried, may have been brought nearer to the surface. The seeds of some species require light for germination, so if they were brought to the surface by raking, this may have further promoted germination in the hidden seed bank.

Seedling density may also be higher in Square 3 simply because there are more plants which have already regenerated in this area (particularly the ground flora) to provide additional seed sources. Conditions are also likely to be more favourable for seedling growth in Square 3 because the area has had longer to recover from the effects of the Rhododendron cover.

It is likely that the removal of the leaf litter layers in Squares 1 and 2 and the consequent disturbance of the soil and its seed bank, by the vigorous raking is also responsible for the rapid stimulation of germination in Areas 1 and 2. Seedling density was lower in Square 1 than in Square 2 (Figure 7). The soil in this region was very shallow and stony, so the lower seedling density may be a reflection of the poor quality of the substrate in this region.

Area 4 shows a notably low seedling density in comparison to the other regions (Figure 7). It is likely that this is due to the fact that this area was the last to be raked and cleared of leaf litter.
