Beavers have been returned to the South-down national park after a 600 year absense

Having been released near Petersfield in the South of England, they will be tracked by a team of academics, to make sure that they survive and thrive.

These beavers will help with the rejuvenation of a wetland area on the river Meon. Currently, the area consists of a straight section of the river, with a sort of duck pond beside it, however, once the beavers get to work, this will change dramatically – turning the pond into a series of ponds, and making it suitable to house a wide variety of British wildlife.

As found elsewhere in the UK, the beavers are likely to have a rapid impact on water quality (for the better). A second pair were introduced to an estate near Basingstoke just last year (they had their first kits in September this year).

As in other parts of the country, these beavers will spread out from where they have been reintroduced (if allowed) and are likely to link up with other populations, such as the Devon beavers, within a small number of years – it seems likely that without a sustained attempt to remove the beaver once again, it is only a matter of time, before they spread to all parts of the UK.

Apart from the joy of knowing they are there, there are many positive impacts of their presence: they will reduce flooding (areas that they do flood with their dams, are places which we likely should not have built anyway), clean water and create habitats for many other creatures. Perversely, they have also been shown to help forests recover (by creating a mosaic of different habitats) and therefore should be a positive for the forestry industry in the UK, despite fears to the contrary.

Could the recovery of the Goshawk save the red squirrel?

European Goshawks were extinct in Britain at the end of the 19th century (and remained rare for over half a century) but in the last 50 years have made an incredible comeback. In the new forest, in the south of England, there are thought to be hundreds of pairs living wild.

In Thetford forest in Norfolk, an estimated 52% of the goshawks diet was grey squirrel. While it is true that they will also take red squirrels, these are generally better at escaping. More importantly, it is thought that Goshawks could be used to stop the grey squirrels population from growing any further.

As I have written before, the pine marten is also important for the recovery of the red squirrel, as it is far more successful at hunting grey squirrels, and they generally do not cohabit in any part of the country.

This will likely not eliminate the direct need for grey squirrel population to be culled by humans, far from it, but may well help towards the idea of giving red squirrels breathing room.

Sweden is often held up as the way to do forestry, but is the bubble about to burst?

Most of Sweden is still covered in forest. I have visited the country, and have enjoyed exploring it. Never the less, an alarming study has shown that most of the forestry – about 97% relies on clear cutting ancient woodland, and then replanting it with monocultures of trees, not all of which are native.

Sweden so called environmental forestry may be nothing of the sort. Clear cutting old growth, and replacing it with non-native monocultures is not the same thing

Clearly Sweden must buck its ideas up, or change fast. I have commented on the low density of bears and wolves. In the past, this has been put down to the countries large number of hunters, but perhaps this is an early warning about what is happening to these forests.

Might this hit the IKEA brand? certainly if they wish to survive, they are going to have to change their behaviour dramatically.

A trial of Silvopasture in Devon

I wrote about Silvopasture recently, there is now a trial going on down in Devon. A farmer is now planting huge numbers of trees sparsely across his land. Each row has trees roughly every 6m and each row is roughly 14m apart.

This will produce a patchwork of shade and sun.

Trees being planted are Oak Aspen and Alder – native British species.

Neighbours have suggested that he is mad, and concreting over his land would have the same benefit. Of course common sense would suggest that concreting over the land would leave far less grass than sparsely planted trees but there we are.

5600 trees will be planted across his 165 acre farm. He is taking part in a 12 year trail to see what benefit Silvopasture can have. The expectation is that the environment will benefit, but that there should also be increased productivity for the farmer.

If it can be shown that grazing sheep under sparse woodland increases yield, roughly 63% of agricultural land could have similar treatment. This could amount to hundreds of millions of trees across the country.

Studies elsewhere suggest benefits include reducing flooding increasing drought resilience, improving animal health and weight, as well as boosting biodiversity and sequestering vast quantities of carbon.
