The end results of habitat management
often seem to pass by in a flash in June.
This week offered the opportunity for a bit of speedy site checking to
see how target species were faring. A
quick look at North Warren found 40+ spikes of Sand Catchfly, maintained in its
favoured bare patches by a bit of raking and over-zealous cyclists. Who says disturbance is bad? A whizz by Minsmere produced a distant Savi’s
Warbler and, more impressively, a Bittern booming out in the open in front of
the Bittern hide, where else?
Fen Orchids are just coming into
flower. The remaining Norfolk plants are
found on just four sites, with the majority now under the management care of
the RSPB. Since taking over the
management of Sutton Fen, experimental cutting of 80 blocks of fen on a variety
of rotations has seen the number of Fen Orchids rise, with an estimated 1,200
plants last year. Other fen specialists
such as the Round-leaved Wintergreen and Crested Buckler Fern seemed to be
doing okay. Shallow turf ponds have also
been cut to re-establish early successional conditions and now have the Shining
Ramshorn snail in residence.
Cranes are busy at their usual sites,
with their usual mix of problems. One
pair had already lost two clutches and have probably given up for the year; others
have young chicks in tow but still are a long way to fledging. The breezy conditions were not ideal for
Swallowtails but several were seen briefly at both Sutton and Strumpshaw Fens. Much better was a ready to emerge pupa
pointed out by the warden.
