The bittern - benefiting from habitat creation initiatives |
THE UK’s bittern
population is now higher than at any time since the 1800s.
That’s according to an announcement this week by the RSPB
which says the progress “demonstrates that it is possible to bring back species
from the brink”.
Thanks to funding
from the EU, a range of organisations have participated in numerous initiatives over the past 17 years to encourage these elusive reedbed
birds.
In 1997, at the start of the EU’s bittern project, there
were 11 reported booming males at seven
sites.
This year, there were 140 “boomers” across 61 sites.
Of these sites, 14 are current or former gravel pits, brick
pits or open coal mines, demonstrating the important role restored quarries and
similar sites can play in securing the long term future of bitterns and other
wildlife.
RSPB Minsmere in Suffolk used
to be the stronghold for this bird for many years. But with the effects of
climate change such as loss of freshwater coastal wetlands in mind,
conservationists realised that it would be better if a number of suitable habitats
were available in areas that were safe from sea level rise, and spread across
the country, to ensure the bittern’s future.
This year, the highest number of bitterns recorded was at at
RSPB Ham Wall, inland marsh habitat in Somerset,
where 20 birds were booming from the reeds.
Somerset
now has England’s
largest bittern population.
According to the RSPB, action for bitterns has also benefited other
reedbed species such as water voles, great white egrets and rare small dotted
footman moths.
Functioning reedbeds also provide free services for people,
including water filtration and flood mitigation.
Says the charity’s Director of Conservation Martin Harper: "The bittern success story should give hope that it is possible
to recover threatened species and that it makes sense to protect the laws that
protect nature.”
It is thought the
Lincolnshire Wildlife Trust has played a role in supporting bitterns in the
north of the county, but it is not mentioned in the RSPB statement. On the
basis of the latest Lincolnshire Bird Report (2012), the species seems to be
struggling to secure a breeding foothold.
The RSPB statement says: “Across the country many
conservation groups and private landowners have worked together to bring
bitterns back.
“These include, for example, the National Trust at Wicken Fen, Natural
England at Shapwick Heath, and Yorkshire Wildlife Trust at Potteric Carr plus Norfolk Wildlife Trust, Suffolk Wildlife
Trust, Lee Valley Regional Park Authority, Herts and Middlesex Wildlife Trust,
Sussex Wildlife Trust, Lancashire Wildlife Trust and Somerset Wildlife Trust.”
