Should we be subsidising this action?

Farmers in the UK receive subsidy every year called the “The Single Payment Scheme”. The scheme is not linked to production but farmers must meet “cross-compliance” standards and demonstrate that they are keeping their land in “Good Agricultural and Environmental Condition”

The standards of Good Agricultural and Environmental Condition relate to issues of soil erosion, soil structure, soil organic matter and set minimum levels of maintenance so as to avoid the deterioration of habitats and protection and management of water.

In Suffolk these standards are clearly open to interpretation. These photos are typical of the work being done during the winter on many farms receiving the “The Single Payment”.

Ditches are dug out sometimes over 3 metres deep into the clay subsoil. Old over grown hedges are cut down to ground level with the exception of the odd “standard tree”, any hedge re-growth is prevented by annual cutting. Green field edges that are part of “cross-compliance” are reduced to liquid mud by ditch spoil and heavy hedge cutting tractors.

On most Suffolk arable farms over 95% of the land is in arable production and of little wildlife or environmental value. If the remaining 5% of land consisting of hedges, field edges and ditches is heavily managed in the winter these farms become wildlife deserts.

The improved drainage that results from the deep bare channel like ditches runs straight into rivers and then into the East Anglia fens which at sea level are very vulnerable to flooding. The bare or sparsely vegetated ditches also lead to increased nitrogen pollution.

The activity shown in these photos are not a once only action. Ditches are scoured regularly leading to increased run of water at flood prone times. Hedges and verges are cut back hard on all sides every year seriously degrading their environmental and wildlife value.

It is hard to see how this sort of action meets the spirit of the cross compliance standards and should be rewarded with public subsidy. In addition this farm is used for farm demonstrations by Frontier Agriculture Ltd and is visited by many farmers. It is hard to see how some of the management practices on are in line with Frontier’s stated environmental policies.

March a critical time for Barn owls

Barn owls hunt by sound and fly silently but their silent feathers are not waterproof. This is why the Suffolk Barn owls have been hunting at all times of the day for the last few months, they are trying to avoid the rain that soaks their feathers and wind that stops them hearing small rodents. However, up to now I have often seen them catching field voles, this makes a change from the lack of voles last spring.

March and April are important months for Barn owls if they are going to breed successfully. The females must gain enough weight to be able produce eggs later in the spring. As we run into March in Suffolk the mornings have been frosty and even snow is forecast, this makes a change from the mild stormy weather we had up to now. It remains to be seen if the changing weather effects the field vole population, this in turn will decide if the Barn owls have a good breeding year or not.

So far this March the signs are good and the Barn owls are still catching plenty of voles. I will keep watching, the next few weeks will dictate the Suffolk owls have a good year or not.

 

Leaping and Boxing – About to take off?

Although the last week has been cold the sun has come out and the rain stopped, day-light has pulled out to be longer than night time. The Brown hares at Halls and Little Haugh farms have started to be much more visible. During the short winter days they rest in the tangled hedge bottoms and thick field margins only coming out to eat in darkness.

The drier fields and growing winter cereal crops have drawn out the Brown hares into the early spring sun. They are often in pairs or sometimes bigger groups of more than ten hares. Prospective couples have started to chase each other and I have already seen two pairs mating in the distance.

It will not be long before boxing will become a common sight on the farms but, boxing at Norton is more likely to be seen in later spring or early summer. The recent cold dry weather has slowed growth but the winter crops are well advanced and any warmth and sun will make them race away hiding the hares in long growth.

On a practical note most of my brown hare photos are taken from mobile hides, these do like the strong winds and can often be found on the other side of a field tangled in a hedge if left out in windy conditions.

Hopefully as the weather calms down and days get longer the hides can go back up and I will be able to watch and photograph the Hare’s spring boxing and other action. Keep coming back to see what happens.

Bird ringing at Halls farm

Large flocks of finches and linnets are disturbed when I walk round Halls and Little Haugh farms; on one water logged field last winter more than 60 snipe were counted as we squelched across it. There just seem to be more birds about both species and numbers than there are on most Suffolk farms. However, “more about” and one off counts are not good scientific evidence and do not prove anything.

John Walshe started working at Halls farm a year ago as a forklift driver, John has an enviable knowledge of birds and is a licensed bird ringer. John started to regularly hang out long mist nets on the farm, the caught birds are identified, aged, sexed and weighed. John is part of a UK wide volunteer army recording much of what we know about the bird population, the British Trust for Ornithology collects, interprets and reports this information. Ringing is only one method used, the most recent and comprehensive Breeding birds survey was published in 2013. This was based on volunteers recording the birds seen in 1 Km squares four times a year for three years. Government and other organisations use BTO bird surveys to help make conservation and other environmental decisions.

Over the last year John has built up a detailed picture of the birds at the orchard at Halls farm; species, population, resident or transient and breeding is indicated from the information he has collected. Winter 2014 / 15 John caught 21 species and 625 individual birds. Some caught birds already had rings. A goldfinch had been ringed in Yorkshire, several green finches were ringed in other parts of Suffolk.

I found it striking how many species stay in the same place. John is ringing in the orchard at Halls farm, a two hundred metres away there is a flock of more then 20 reed buntings in a hedge and game mix field, John only ringed 5 last winter showing that they hardly move from one location. The farm has many breeding skylarks that are resident all year, none were ringed last winter.  This indicates how important even small patches of land are to many species, hedges trimmed at the wrong time or verges cut down will destroy food and shelter for local bird populations.

Trapping and ringing birds is a useful tool for mapping populations but has limitations and other survey techniques can be used like the counting used in the BTO Breeding birds surveys. Ringers are always adamant that trapping and ringing does no harm. However, being caught in a net then handled and ringed should be assumed to have an effect and there should be clear reason before any bird is ringed.

 

Too often trapping and ringing is undertaken by well meaning people who although licensed, act independently, “surveying their own patch” almost as a recreational pursuit. The decline in bird populations has been extremely well documented and it is difficult to understand why the same issue has to be repeat ably shown. Arguably the BTO should only issue ringing licences if there is need for specific information to fill in gaps in our scientific knowledge. For example; “bird in hand” photos on Facebook and birding websites of rare migrants caught in coastal ringing nets after a long over sea flight, seems more like “trophy ticking” than the collecting of useful scientific information. Ringing as a useful tool is in danger of being undermined by over enthusiastic individuals.

John’s evidence from ringing and recording at Halls farm has confirmed that the farm orchard has a greater than average number of bird species. This helps show that Halls and Little Haugh farms partnership with Jordan’s cereals farms which includes devoting 10% of the land to wildlife conservation is helping to increase wildlife diversity.

Late summer hares, Norton Suffolk

By August the oil seed rape and many of the oats fields have been harvested and the brown hares move back into the game cover planted round the farms. These hares were photographed  early August in and around the game mix areas.

The Pond

The pond is in a corner where two rides cross in Pakenham Wood. It was dug out four years ago one morning when Robert had borrowed a digger, it is about 30 metres by 6 metres at its widest point. The land in the wood is heavy clay so water naturally fills any deeper depressions.

We had come up to the wood because Jordans, who are supplied with oats from the farms, want to change the way the 10% of the land managed as wildlife habitats are assessed. Alison Cross from the Wildlife trusts and Anthony Goggin from Leaf wanted to look at what is being done on the farms.

In July, Pakenham Wood has Silver-washed Fritillaries and White Admiral butterflies gliding up and down the rides; these had already distracted us. We then got to the pond, at first glance nothing special, reeds growing at the deeper end and lower plants in the shallow end. Then the chaser dragonflies started to dip eggs into the pond surface, the more delicate damselflies could be seen and water boatmen were on the surface. We stood and watched.

Reeds are growing out of the deeper water, and despite the still air the dead brown leaf on the reed base moved and then split open. This was a dragonfly emerging from a larval stage that had climbed up the reed. This had a near hypnotic effect on us, as within 30 minutes the small stubby green wings had grown to full size and dried, the dragonfly suddenly took its first confident flight. A closer look at the reeds revealed more hatching dragonflies and of lots their empty brown cases.

The pond water is clear and we could see the larval dragonflies climbing up underwater but they were not alone. The small four legged animals were Great crested newts and it is likely that we were the first people to have seen them in this relatively new pond. The newts shared the underwater space with round water beetles including the large great water beetle.

The plan had been to start see how the different habitats on the farm complemented each other, for example how the thick hedges with wide margins acted as wildlife corridors through the farm. However we had spent nearly two hours transfixed by a new small pond and lunch was waiting at the pub.

After lunch we tried to be more focused, looking at the way the farms growing Jordans oats can get maximum wildlife benefit and diversity from the 10% land not in agricultural production. Despite the farm being part of a game bird shoot we came across a flattened field margin. This, dead rabbit remains and a characteristic smell were sure signs of young foxes playing in July sunshine.

Back at the farm office Robert the shoot gamekeeper was vaguely interested about where the fox litter he had seen in the spring had moved to but he was far too busy with young game birds to be bothered by young foxes. As we told him about the pond he let slip one of his rare smiles. The pond had just been an afterthought, just making use of a digger being used for drainage work on the farm. Like us, Robert was amazed by the life we had seen. Alison Cross suggested that he dig another pond close by which will take over from our pond as it silts and chokes up in the next few years.

What we had seen on one July day was how a couple of hours digging a new pond has been richly rewarded and that tolerance of untidiness allows wildlife, including foxes, to thrive on two productive farms and a commercial game bird shoot.
