Silklake Quarry (Bumpers Lane development) and Bottom Coombe Quarry - seed sowing in the newly scraped areas.

Portland - Silklake Quarry and Bottom Coombe wildlife conservation sites


We have several areas of recently cleared ground here to spread with locally collected wildflower seed. And there is more at Bottom Coombe nearby too.

Meet at the entrance to the site at 9am, with refreshments and lunch – or walk to find us if you arrive later.  We can supply necessary tools. It helps with planning (but not essential) if you let me know that you are aiming to join us.

We cleared this area earlier this year and will be sowing seed here. Mainly vetch seed – ideal blue butterfly larval foodplants.

The excavator scraped the area clear, then spread 150-200 mm of limestone chips over it.

This is the area we shall be seeding with mixed seed harvested locally

This is bare area we sowed with kidney vetch last season, it was growing in profusion this summer!
