Balancing the need for new homes with wildlife protection (October 2014)

This entry comes from the fantastic Writtle conservation team and looks at modern issues surrounding wildlife and the demand for new homes.

------------------------------------------------------------------------------------------------------------------

Conservation is a hugely diverse and interesting subject and Essex has recently been at the forefront of one of the most discussed initiatives of recent years.

People are familiar with the approach to conservation taken by organisations such as the RSPB who are probably best known for nature reserves, which are specially managed, often for rare species.

But that does not mean that even the land immediately adjacent to your own home might not have wildlife interest, for example, reptiles, butterflies and unusual plants. Consideration of the wildlife on any site has been an integral part of the planning process for many years and has come to the forefront as we face the needs to build new houses. 


The Government has been keen to get the economy moving and meet the demand for more houses and, consequently, has been piloting a concept known as 'biodiversity offsetting'. This is a method whereby damage to or loss of wildlife habitat is 'offset' by creating habitat elsewhere as part of the planning agreement. Essex, arguably one of the most biodiverse areas in the UK, has been one of six areas piloting the process.

On the face of it, offsetting seems like a pragmatic solution to a problem which is felt especially keenly in counties such as ours and its supporters claim it offers the benefits of larger and 'better' sites for nature. But the idea has run into some hostility from those in the conservation community and it has been suggested that offsetting cannot work for a number of reasons, among them the fact that natural communities of plants and animals are complex and take time to develop. 

The main issue for everyone is how to balance one set of values against another. For example, last year a huge housing development in Kent was rejected (although planning application submitted by the developer remains in place) due to the extraordinary number of Nightingales found on the site. Was this a "good" decision or a "bad" one? The problem seems to be that we want everything - we demand housing but we also want our wildlife protected. 

So before you think that conservation is something which happens only on a nature reserve, remember that one of the most heated wildlife arguments for many years is currently being acted out right on our doorstep.

Writtle Wildlife Watch (June 2014)

Writtle Wildlife Watch returns for June! Alan Roscoe is at it again and once more keeps track of the fascinating wildlife on campus! 

--------------------------------------------------------------------------------------------------------------

I hope most of you caught up with the recent Springwatch programmes from Minsmere. Apparently the visitor numbers were up a staggering 50% as a result of the TV coverage although you do have to wonder whether the additional visitors were more excited about seeing Chris Packham than the wildlife!

It is good to see the BBC committing so much resource to programmes like this although (curmudgeonly grouch face on) just occasionally I wonder whether there is an overemphasis on the birds and the mammals – which, of course, the public enjoy – at the expense of the plants and other groups such as lichens and mosses. These are just as fascinating as the popular animal groups but, perhaps because they do not move, they are less appealing to the general public.

We monitor a range of animal species on our own College estate but we also keep an eye open for unusual plants and now is the best time of year for many orchid species. We are lucky enough to have both Bee Orchid and Pyramidal Orchid on our estate and, due to the sharp eyes of a colleague (well spotted Roy), we have found a new site for them this year. Pyramidal is pollinated by moths and butterflies which visit the plant not for nectar, but for a watery liquid which is found inside the ‘spur’ part of the flower. Grains of pollen are then picked up on the insect’s tongue and the perfect symbiosis of this particular species and its pollinating insects was even remarked upon by Charles Darwin himself.

Writtle Wildlife Watch (November 2013)

Writtle conservation expert, Alan Roscoe, has been busy putting together November's wildlife watch. This month provides a fantastic entry about crayfish! 

-----------------------------------------------------------------------------------------------------------

Your blogger is very keen on crayfish sandwiches but his interest in these animals extends far beyond what he had for his lunch.

The chunky crayfish which turn up in sandwiches are commercially harvested American Signal Crayfish but there is a dark side to your lunchtime snack. In recent decades these non-native animals have escaped from captivity but, in doing so, they have brought problems for their smaller British cousin, the White-clawed Crayfish.

Our much more delicate native species has succumbed in huge numbers to a disease carried by the American species and the situation is now so grave that some of the White-clawed populations have been removed from their natural homes and re-housed away from the threat in so-called ‘ark’ sites.

This month Writtle Conservation students have visited one of these sites to help monitor the success of one of these re-homing projects. In conjunction with Essex Wildlife Trust, Essex Biodiversity Project, wildlife consultancy EECOS and the Environment Agency (yes, it takes a lot of people to save just one species!) our students trapped several crayfish and took their vital statistics. Work like this is essential to help monitor whether the population remains viable…. but it also gives Writtle undergraduates valuable hands-on experience and a head-start in the conservation sector.
