Hidden Eyes

Recently trail cameras have revolutionized the way we understand animal behavior and even rediscovered  animals that we thought were extinct. It’s helping us understand the ranges of many species, especially species that are hard to see. If you watch Planet Earth or Countryfile you will often see footage taken on trail cams that have shown that certain species have persisted or recolonised areas that previously thought devoid or unsuitable.

Pine Martin in this country are a good one. Their range was previously more or less confined to Scotland and some parts of mid wales. It has now been found that there is a good population in Shropshire and even one in the New Forest. Whether these are natural is yet to be determined. It is unlikely that a population has persisted in the New Forest for hundreds of years, and even less likely that they have recolonised. But you never know and it’s through the implementation of new technology that these things are starting to become apparent.

I use trail cameras regularly at work as they allow me to get some nice shots of animals that are hard to see but they are also useful for monitoring areas. For instance Swanwick Woods is surrounded by a large electrified fence. Yet there is signs of deer browsing inside. Putting cameras up will allow me to judge the population size and assess whether it is necessary to protect coppiced trees from browsing.

Sightings week ending 04/12/2016

Its been a cold an frosty week but the weather hasn’t really pushed the birds down. Still very few Fieldfare or Redwing through a few have been spotted at Farlington. The forecasted Waxwing still haven’t turned up yet.

 

Farlington

Lots of wader as usual especially with some quite high tides. There are still a couple of Spotted Redshank on the stream a long with a large number of Pintail and Teal. There has been a large number of Avocet in the channel west of the marsh. Largest count so far has been 53.

The Short Eared Owls are still there, three of them and a couple of overwintering Dartford Warbler can be seen in the point field. A Barn Owl has also been seen in the bushes area.

Swanwick Lakes and Hookheath

Both sites have the usual woodland mix. Lots of Goldcrests, undoubtedly with some Firecrest in there. A number of Marsh Tit have been seen on both sites.

Call for Wardens

We would like to recruit some more wardens to help out down at Farlington Marshes. We would like to promote the site and and enthuse people about what a great place the marshes is.

If you like Farlington and would like to get involved please email me

Christopher.Lycett@hiwwt.org.uk

No experience of birding, wardening or anything else is required, just some enthusiasm and willing to interact with members of the public.

The main duties of the role will be:

  • Patrolling the site, dealing with or reporting any incidents or issues to staff members.
  • Providing a friendly point of contact for members of the public who may have questions about the site.
  • Relay information and updates about the site from staff members to the public.
  • Keep an eye on the Livestock whilst present.

There are currently no strict time constraints on when you do the wardening but this is an evolving role which we hope to develop in the future to become a bit more structured so as the site has a volunteer member available during the core times.

 

So if you have a little bit of free time, as little as one day a month or as much as one day a week and would like to get involved please get in touch.

Beautiful Biddenfield

wp_20161202_11_42_52_proDuring the winter we need to remove the cattle off many of our sites, as to persist there they would need to grow flippers or at least very large feet so they don’t sink. Hookheath is a flood meadow, Farlington is a marsh and Swanwick lies on dense, sticky clay. So all in all, not the best place for heavy footed bovines to hang around all winter. We are therefore very lucky in that we have Biddenfield, just down the road from our offices to overwinter some of the stock. Our Swanwick guys were taken down there at the end of September and have been getting along very well. They sprung over to see me this morning.

Biddenfield is a spectacular site where the landowner has really gone to town in providing for wildlife. Not only is there beautiful woodland surrounding the site but there is some well managed pasture and the largest area of wild bird seed that I have ever seen. Hopefully given a cold winter, this will provide some much need support for our farmland bird species. I saw large numbers of Reed Bunting, Goldfinch and Green finches down there today.wp_20161202_11_43_26_pro

Acting Like Elephants

csc_0396I often wonder what would happen to our landscape if humans suddenly vanished from the Earth. How would the landscape change? Given the amount of invasive plant species we have I’m sure a woodland would develop with a Rhododendron dominated mid-layer and riparian woodland with thick bank of Japanese Knotweed and Himalayan Balsam. That may be a little pessimistic of me and besides,  given a thousand years or so, this would no doubt balance out, as nature takes on the challenge of creating a functioning, self balancing ecosystem.

This is one of the things that interests me most about nature, it’s ability to choose what is best for itself and sustain a course that eventually benefits such a wide range of biodiversity. It may not be apparent at first as, if left to its own devises, we would lose much loved habitats such as heathland and flower rich meadows, habitats that we praise for their abundance of biodiversity. They are however man made. Products of a system that once supported our needs for food, fuel and building materials.

Another thing that really interests me is paleoecology. This is the study of extinct ecosystems or the way they functioned in the past. This has influenced the new big buzz word at the moment doing the rounds in the ecological world. Rewilding. This is the process where you restore the key components of an ecosystem, the large herbivores,  the predators that control them and then you simply step away and let nature take its course. As ecosystems once were, unspoiled and unaltered.

If you adhere to the Vera model (a theory created by Frans Vera), then what would happen is the creation of a fluid mosaic of woodland, punctuated by grassland, scrub and wetlands, continuously shifting with grazing pressures and storm events. Species would create holes in the woodland that would fill with wildflowers and grasses or heathland species. Over time successional change would cause the creation of scrub and then eventually high forest where the process would repeat. In some areas where grazing pressure is particularly high, the habitat would be maintained at certain stages. This has been shown in places such as the Oostvaardersplassen in the Netherlands, where a number of species where reintroduced and a policy of nonintervention was adopted.

But what could cause deforestation of large trees?  I recently went to South Africa and witnessed a landscape of scrub, with large openings of grassland. Very few large trees persisted. This was the doings of Elephants. They can’t push over a large tree but they tear the bark off and cut off the supply of water and nutrients, flowing up and down the trunk, thereby killing the tree and dramatically changing the landscape.

But we don’t have elephants in the UK. Well we don’t now. We used to have several species of temperate elephant living in northern Europe. There is some really interesting evidence of this in every woodland in the UK, even possibly in your garden. Trees have adapted to the onslaught of large herbivores. Mid layer species such as Hazel and Blackthorn can regenerate from any point that it is broken. This is an adaptation from being repeatedly snapped. The latter of these species has thorns that are up to two inches long. Perhaps a little over the top for a few nibbling deer!

The point of this long ramble is to give an idea of what we are looking at with our woodland management. To the best of my ability I try and replicate a natural system, a tricky undertaking where you either have too much grazing or not enough and where you have to fill in the role of multiple species doing multiple jobs. I don’t really want to make the headlines for introducing large herbivores into a small reserve in an overcrowded south coast so when we go into an overgrown woodland we look at opening it up in a way where I sit there and think “what would an elephant do? What looks tasty?” Unfortunately no matter what I do, it will never be a truly natural system but it hopefully will bare some resemblance and therefore maintain all the benefits of a woodland that nature has created.

With that in mind we have spent a lot of time in Swanick recently, doing some large scale felling works. With many woodland sites across the country, at some point in the last hundred years or so, management stopped. This has led to the uniform growth of trees so that there is a thick canopy of predominately oak that is all at one level. Under this there may be some large, over-stood Hazel struggling on in the gloom of the understory. It looks dramatic but what we have had to do is come in and remove some of these larger Oaks. This isn’t something that we take lightly as I have a particular soft spot for Oaks and ones that are a hundred years plus, well they deserve some respect. It is however a wider picture thing and hopefully the benefits of a thinner woodland, one that resembles a more natural state, one that looks like it was engineered by nature, will have huge biological gains in the future.

We were lucky to have a great team with us last week. Over from the Isle of Wight we had Andy and the woodland apprentices. 

Swanick Woods is within the the NATS (National Air Traffic Control) high security compound so working in there can be a bit tricky. Thankfully NATS are fully supportive of conservation works around Swanick and have been really helpful in getting us in and out of the site.

Arriving on Wednesday we were greeted by a lot of bramble and some very thick woodland.

wp_20161125_13_52_46_pro

After three hard days work we now have a nice sunny ride back and some much thinner woodland around the edges. Hopefully this will be a great area for butterflies. Purple Emperor are found in this part of the site. 

wp_20161123_11_22_20_pro

As the site is completely fenced there is little deer browsing so a thick mid-layer has developed in some parts. It is however all of the same age, blocking out any light that makes it past the canopy of Oaks. Te result is that the only thing that grows on the forest floor is Ivy.

wp_20161125_13_53_00_pro

Acting like Elephants we came in, knocked a few of the larger trees out to great a few gaps in the canopy and then thinned throughout the Hazels, taking them out at random, leaving some young ones and some old ones to give a varying age structure. Standard coppicing procedure generally takes out an entire area to give a large light area called a coup. This has great benefits to wildflowers and invertebrates but what we are trying to achieve in this wood is a network of smaller patches throughout the woodland.

wp_20161123_11_22_09_pro

Very thick Birch and Ash regrowth in one area that had been clear felled perhaps 15 or twenty years ago. These pioneer species tend to be the first to colonise and with the appropriate grazing pressure they may have grown less uniformly.

wp_20161125_13_53_15_pro

We have now opened up the ride a bit more and thinned throughout, removing almost two thirds of the trees.

Small Things

We have continued working at Hookheath recently, pushing all of our resources into it so as to get the work done before we sink. It’s nice to take a break from chainsawing for a moment and have a wander around and see what you can find. I came across a couple of very small fungi which made for a few nice pics.

Yellow Antler Fungi – a type of coral fungus

Yesterday we were surprised by something else very small. A newborn calf was unexpectedly born at Southmoor. We went down to check it, all seemed fine, a little wobbly on its legs but fit and healthy.  Very cute!

Sightings week ending 13/11/2016

Farlington

Lots of birds as usual , though the water on the lake is high again causing the birds to roost further up the stream,

The Short Eared Owls are stealing the show as usual with 3 as a max count at the moment. As they fly over the marsh they constantly set off Snipe. Two Spotted Redshank tonight and three Avocet on the stream, though max count of the latter is 6. Loads of Wigeon feeding in the fields with the Brents starting to use it now. There were 28 Shoveler on the deeps and looking out to the harbour from that point there were 32 Ringed Plover.

Bearded Tits are quite vocal and can be seen above the reed. I have filled the feeding platform by the building with grit and some seed so hopefully there will be some nice shots there.

Hookheath

Last two times I have worked down there, a Raven has flown over. Bullfinches are present constantly as well as decent numbers of Marsh Tit. There is lots of fungi as well.

Southmoor

The usual mass of waders and wildfowl at low tide.
