Tree Health Pilot Scheme, targeting pests and diseases.  Finding out about the THP and SPHNs

Tree Health Pilot Scheme, targeting pests and diseases.  Finding out about the THP and SPHNs

by Ruth, 26 July, 2023, 1 comments

We first became aware of the tree health pilot (THP) scheme in 2021 when we received a Statutory Plant Health Notice (SPHN) for trees infected by one of the specified pests. The THP scheme has been designed to help slow the spread of pests and diseases affecting trees in England. There are grants available for larch trees with Phytophthora ramorum, spruce trees affected by Ips typographus, sweet chestnut trees with Phytophthora ramorum or sweet chestnut blight, oak trees with oak processionary moth (OPM) and ash trees with ash dieback. In our case, the Larger Eight-toothed Spruce Bark Beetle [Ips typographus] had been found in the Norway spruce and we were instructed to fell, move, process and destroy all spruce trees in the defined area of the wood. Strict but clear directions were given regarding the ‘how, when and where’ for the felling and processing. An initial site visit and ongoing support from the Forestry Commission and their Plant Health Forestry Team allowed us to follow the process of applying for a THP grant with ease. We submitted the application and received confirmation that the grant application was successful, at which point it was over to the team undertaking the felling. Once complete a final inspection from the Forestry Commission took place to ensure we adhered to the agreed method statement (as specified in the SPHN) and then we were able to submit the claim. This claim was processed and received – all within approx. 3 weeks. Fast forward to 2023. One of the woods we are managing in the southeast (which lies within the Ips typographus demarcated area) has a small stand of Norway spruce (approx. 0.5 hectare). Some of the trees are damaged, stressed or dead, and at risk of providing the right conditions for the eight-toothed spruce bark beetle. Advice from the Forestry Commission is: How does felling healthy spruce help the situation? This reduces the opportunity for colonisation [of the beetle] and may sometimes be required as a precaution to ensure that trees that could be potentially infested are removed. Removing spruce as a host from the demarcated area entirely will limit the possibility of populations of Ips typographus establishing and prevent spread to other areas. Predicted climate change means that what is currently healthy spruce may not remain so over future years, hence early felling could reduce the risk of these areas becoming future outbreak sites. We decided to investigate whether the THP scheme could support the proactive felling and extraction of the Norway spruce. We submitted an Expression of Interest for the THP scheme, the Forestry Commission undertook a site visit and were able to confirm there was no Ips found in the wood, and we were eligible to apply for the grant. We concurrently applied for a felling licence to clear fell the compartment of Norway spruce. It is worth noting, if an SPHN is served then normally there are no restocking conditions applied however restocking and maintenance grants are available to support restoring woodland In this case there are restocking conditions in line with the felling licence – an opportunity to plant and enable native broadleaves to thrive – that can also be grant-aided. An application for the THP scheme was submitted and we subsequently received a grant offer which was accepted. What next? A pre-felling survey was required in order to determine pest freedom for Ips typographus, and the authorisation for harvesting operations remains valid for 3 months. [caption id="attachment_40238" align="aligncenter" width="675"] Galleries formed by the beetles[/caption] An inspection for Ips typographus will need to take place before any felled timber can be taken off site – the advice is to fell and move the timber quickly rather than leaving stacks in the wood. The felling commences this week and should only take 5 days, and we plan to restock with native broadleaves over the winter. The Forestry Commission has produced a very useful guide Ips typographus: Guidance on the movement restrictions of spruce trees - Forestry Commission (blog.gov.uk) but throughout the whole process the Forestry Commission and Plant Health team have been really supportive and quick to answer queries about Ips, the THP grant scheme and the forestry operations. My advice if you have a stand of Spruce – is to speak to your Forestry Commission Woodland Officer about getting involved with the Tree Health Pilot scheme or visit their website to find out more: Tree health pilot scheme - GOV.UK (www.gov.uk) Last week we hosted a number of people from the Forestry Commission, the Plant Health Forestry team, Forest Research, and DEFRA. They are continually evolving the scheme to understand how best to provide this vital funding to woodland owners to enable and encourage management of spruce and Ips. We were pleased to say they have, however,  not found it in the wood!
Woodland and forest cover

Woodland and forest cover

Compared to some of our European neighbours, it seems that our percentage woodland and forest cover is quite low at 13%; as was recently discussed on the BBC "More or less" programme.  Only Denmark and the Netherlands have similar low levels of cover.  Finland, on the other hand, has almost three quarters of its surface area covered with trees. After the end of the last ice age, trees gradually recolonised the exposed landscape so that vast swathes of the U.K. were covered with woodland/forest - the wildwood. It might be thought that our current low figure is due to increased urbanisation, road/motorway construction etc. In fact, the tree cover is remarkably similar to that at the end of the first millennium CE. More trees were ‘lost’ in succeeding centuries with the expansion of farming, and trees were harvested for boat building and house construction.   The Mary Rose was built using oak and elm. It was the first big ship of the Tudor naval fleet.  It has been estimated that over 600 trees were needed for its construction; that is equivalent to about 16 hectares of forest/woodland. Wood was also used to produce charcoal, which was used to smelt metals, particularly iron.  The history of charcoal burners in the New Forest is well documented. Many woodlands / forests were the preserve of the landed gentry and the aristocracy and reserved for deer hunting.  Anyone caught killing deer or boar from such woodlands could suffer terrible punishments but would more likely be fined.. Woodland and forest continued to be depleted so that by the end of the seventeenth century, the percentage cover had fallen to 8%. At the beginning of the twentieth century, the figure stood at a pitiful 5.2%.  The Asquith administration in 1916 established a committee to report on the country’s woodlands and timber supplies.  This lead to the setting up of the Forestry Commission which was not just concerned with established ‘strategic reserves of timber’ but also trying to create viable communities in marginal areas. Through its efforts over the succeeding decades, the U.K’s area of woodland and forest has increased significantly - though the Forestry Commission’s heavy use of coniferous species (particularly in the 60’s and 70’s) has been criticised.  Coniferous woodland / plantations do not support such a wide range of plant and animal life as deciduous woodland.  However, their current emphasis on diversity (and recreational use) favours a much wider range of species, including broadleaved/deciduous trees and the development of a richer ground flora.
