Observatree Summer Round Up
Forest Research
A busy summer of Observatree activity has seen us out and about up and down the country from shows and events to pest and disease surveys we have certainly had our hands full. Here is just a brief summary of what we have been up to and some of the highlights from the last few months.
July
In July Observatree was called into action to support 2 of the partner organisations in their response to recent OPM (Oak Proccessionary Moth) outbreaks within the South East region, Volunteer Manager Charlotte Armitage shares the details.
Oak Processionary Moth (OPM) is of growing concern in the world of tree health and Observatree volunteers have been coming together to try and help partner organisations tackle this pest.
This year therefore the Woodland Trust and National Trust have teamed up and are utilising the Observatree volunteers and their expert training. Local volunteers in Greater London and the South East who expressed an interest have been assigned high priority sites close to their homes. The volunteers have two major tasks:
- If the site is known to have OPM they need to go and survey and alert site staff to the location and heights of nests so the correct management decisions can be made with regards to the public.
- If the site is not thought to have OPM then site staff need to be alerted as soon as possible if it does arrive to limit spread, so Observatree volunteers will be carrying out surveys as part of an early warning system.
The work of the volunteers is of vital importance to staff that might not have the time or resource to look for this pest themselves. The use of Observatree volunteers in this way illustrates how highly regarded they are for their skills and expertise.
OPM which is predominately based around London and the surrounding areas not only has implications for public health and our native oak trees but also poses a problem for landowners. This is especially true of the Woodland Trust and National Trust whose sites and properties experience heavy footfall during the year. Imagine enjoying a picnic under a majestic oak tree not knowing hairy caterpillars were just above your head. OPM has toxic hairs which have the ability to cause nasty skin rashes, and the hairs can remain toxic in the environment for up to five years.
We decided to kick off this partnership with a networking event on the 9th of July held at the beautiful National Trust venue Osterley Park. Woodland Trust and National Trust staff attended, along with the Observatree volunteers who will be surveying for OPM. The morning started with a presentation about the Observatree project to set the context for site staff. Then Jeremy Dalton the ranger at Osterley Park gave an insightful talk about the life cycle of OPM, management, and some of the research they are undertaking. We then had a long lunch break to allow staff to meet the volunteers that had been assigned to their sites and for networking opportunities. There was lots of chatter over lunch and that element of the day was truly a success.
In the afternoon we went out into the park to see OPM in the field and to learn a bit more about this pest. This session really demonstrated why we need to be vigilant with this pest, the sheer number of OPM nests was astounding and this is a site where they are actively removed during the season. This is why it is so important that we try and limit its spread and keep it contained in the core zone in London, and why the work of the Observatree network is so important.
A special thank you to Thomas Hill and Jeremy Dalton for organising the day.
That’s not all we have been up to though; if you were at the Royal Welsh Show during the hottest week of July then you might have spotted us at the Forest Research stand sweating it out. Even the heat couldn’t hold us back though and we spent a long time talking to members of the public and the forestry industry and gave out loads of our fantastic information over the 4 days.
