Hot day for spraying!

 

These past two weeks have been very busy for our volunteers that have been trained to spray Giant Hogweed near the River Bollin in order to control it.  If you remember (or if not, have a look through our previous posts), 11 volunteers were NPTC trained for their PA6AW certificates, which enables the certificate holder to use herbicides near water.  On 10th and 15th May this training was put into practice!

On 10th May we met at the Green Dragon pub in Lymm who kindly let us use their car park as a rendezvous point, and kitted up to go out and treat the Giant Hogweed in the fields adjacent to the pub, and also those that were affecting the fish pass near Heatley Mill.  The giant hogweed here has been found in abundance over the past few years, and as a project we have not had the resource to deal with giant hogweed in this area before now.  Thanks to our newly trained volunteers we have been able to make great headway here in only one day.  Ten volunteers and five Environment Agency staff came along to help out, and everyone spent the whole day working.  You can see on the map below the area we covered, and some photos showing the extent of the problem.

On 15th May we focused our efforts on controlling Giant Hogweed in Hale where BEACON has worked with other volunteers and contractors in the past to spray the field, woodland and footpath areas here.  On this VERY hot day, four volunteers turned out and again did a good days work.  Access here was much more difficult as was access to water (but we managed!) and everyone did a sterling job to control the hogweed in the field area in the heat.

This is all very important work as it links in with the work other landowners, interest groups and local organisations are doing to control Giant Hogweed on their land upstream of these areas.  Huge thanks to all the volunteers who work tirelessly to control invasive non-native species, and also to the Environment Agency for providing funding to facilitate the training they needed.

If you are a landowner and would like to get involved in the Giant Hogweed control programme for this year please contact us here.

You can find out more about Giant Hogweed, what it does, how to identify and control it here.

Case Study for Collaborative Working

Bankhall Lane Giant HogweedThis year has been a great year for BEACON, but not such a great year for Giant Hogweed!

As Giant Hogweed can be so dangerous to people, causing rashes and burns when it comes into contact with skin, BEACON decided to prioritise this species as one they would tackle first.  You can find out more about Giant Hogweed here.  It is also easier to prioritise areas for control work as Giant Hogweed doesn’t occur throughout the whole Bollin, catchment, the first record of hogweed is near Manchester Airport, and the infestation gets increasingly worse as your head downstream.

 

BEACON Volunteer Giant HogweedThe first area to be tackled on a grand scale was Bankhall Lane in Hale as this was the first area where the Giant Hogweed started to get very dense.  Even to be able to treat a relativley short stretch of the river Bollin took a lot of co-ordination and discussion with landowners and private companies such as United Utilities and Network Rail.  The map below shows you who treated which areas of the river Bollin.  BEACON was able to contribute towards funding contractors to undertake work where the hogweed was very dense or inaccessible.  Farmers and landowners treated Giant Hogweed that was in their fields and ditches.

The results of this work have been amazing!  In just one season the density of the Giant Hogweed at Bankhall Lane has been dramatically reduced thanks to landowners, contractors and private companies working together and treating the right species at the right time.  The photos below show the before and after effects of the work.

This is the pipe line from the sewage works to the river before work started in September 2013, and after work has been completed in September 2014.  This work was undertaken by United Utilities and their contractors.

These are the field margins adjacent to the River Bollin at Bankhall Lane.  The landowner and contractors have undertaken work here to bring the Giant Hogweed under control.  The difference between the two pictures is fantastic!

Thank you to everyone who worked really hard to control the Giant Hogweed here, and we look forward to working together again next year to finish off this invasive nasty once and for all!

Decapitating Giant Hogweed

Return_Of_The_Giant_Hogweed_by_HappyRussiaWork has been done to control the Giant Hogweed along the Bollin by contractors, landowners, volunteers, BEACON and United Utilities staff.  We have started to work from the upstream end of the problem at Bankhall Lane in Hale, and have made our way down as far as Bowdon Sewage Treatment Works.

Most of the Giant Hogweed has been sprayed using a herbicide, and some dug up where the plants have not yet reached maturity.

 

 

 

 

 

However, not all of the Giant Hogweed plants can be treated as there are just too many for us to tackle.  So, one way to prevent the plants spreading is to ‘decapitate’ them, or chop off the flowering head.  To do this you need PPE to stop the Giant Hogweed sap burning your skin, and you need to get the Giant Hogweed at this time of year before the seeds ripen.

Two National Trust volunteers and a member of UU staff, helped out last week on a blisteringly hot day to contol the Giant Hogweed at Bowdon.

You can see here the enormity of the task ahead of us.  Below is a bit of a before, during and after shot of the Giant Hogweed and its demise!

Thanks to the work of the volunteers and staff at United Utilities all the Giant Hogweed in the vicinity of the Sewage Treatment works at Bowdon was ‘decapitated’, which will help them and members of the Freinds of Bowdon Bollin in thier control work next year.
