BSBI member Lin Hawthorne exhibited at the recent Exhibition Meeting and there was a great deal of interest in the work she is engaged in, so I'm delighted that Lin has offered us this guest post:
"Three Hagges Jubilee Wood had its origins in the campaign in
2012 to celebrate the Queen’s Jubilee by planting 6 million trees. The simple
mass planting of trees may well produce a fine forestry stand, but is unlikely
to create the priceless diversity so valued in ancient woodland. Function and
motivations are entirely different. At the outset of the project, our particular
motivations included concerns about the losses of floral diversity during the
last century in our own predominantly agricultural landscape, and it became
clear that we must develop radical strategies to address those concerns.

"Our first decision was that if we were to create something
more complex than a plantation, it must, at least, include the vital ground
flora - so frequently overlooked in new woodland planting. Our ultimate decision
to create a wood-meadow ecosystem distilled the essence of all our concerns
regarding the losses of meadow, hedgerow and ancient woodland since the Second
World War.

Some 22 environmental scientists joined us
in May 2014 to contribute to our developing plans
for the wood-meadow.

"The creation of a woodland ecosystem on former arable is
not a simple undertaking, however, and there is no adequate literature to help
achieve it. Hagge Woods Trust was set up to research, develop and
communicate best practice in the creation and development of such new
ecosystems. The long-term ambition of the Trust is to formulate methodologies
and publish our findings on the creation of new wood-meadow ecosystems.
"We have sought strategies that, if applied in tapestry
across the landscape, would create corridors of diversity to link fragmented
habitats, without significant depletion in area of productive land. They should
have potential for building a cohesive network of high-value habitats,
especially in rural/arable areas, and should ensure that implementation is
achievable by farmers and other land managers. The principles in microcosm
could be replicable on a national scale, providing opportunities to create an
interwoven mosaic of small-scale, biodiverse woodlands on farms, in communities
and schools.

"In planting Three Hagges Jubilee Wood as wood-meadow, the
Trust has created a prototype and research base that combines permanent
grassland and coppice woodland, with meadow margins that transition through a
graduated woodland edge of flowering and fruiting shrubs and small trees, to a
high canopy of forest trees. Although wood-meadows are now rare in the UK,
those extant now provide some of the most biodiverse of wooded habitats. Their
importance is more widely recognized in continental Europe, particularly in
Scandinavia, and in Eastern Europe. They include some of the most diverse plant
communities anywhere: 70 plant species per m2. These are our models and target.
"Early analyses of costs suggest that simple implementation
is possible within existing grant frameworks. The Trust has in place long-term
management plans, unusual continuity of personnel and security of tenure and a commitment
to monitoring changes in diversity over a minimum of ten years. The essential
work of this research, data collection and information management, however, depends
on fund raising activities by the Trust.
"The 10ha site is now home to 10,000 woody natives, set in traditionally
managed meadow based on NVC MG4 (wet) and MG5 (dry) lowland meadows, currently
with over 50 perennial and 12 grass species. The range of flora will benefit
diverse fauna; it does not have a single-species conservation focus. The target
is to achieve 150+ meadow species, by further introductions from wild-collected
seed.

"The primary ecosystem service we wish to provide is an increase
in biodiversity on formerly arable land. All selected flora have known virtues
as invertebrate hosts. Together, trees and grassland form the botanically diverse
base of a food web that will serve a huge variety of birds, mammals and insect
life including, critically, our threatened pollinators".
Many thanks to Lin, who is Project Designer and Manager at Hagge Woods Trust, for telling us more about the project. Do check out their website - Lin's blog is superbly written and posts like this one give you a real insight into what she is trying to achieve. No wonder Prof George Peterken agreed to become a Patron of Hagge Woods Trust!
If you are in the area, why not drop in and see for yourself? Send us some pix if you do! And here is the pdf of Lin's poster at the AEM.
