Blog articles about environmental issues

Posted by on in Environment

The results page has been updated to include results up to the end of August 2015 and a link which will open in a new window can be found here:-


We think that we are starting to see patterns in variations of invertebrate populations and should be getting more detailed information from the Environment Agency as to the life cycles of the different species that can be found. We are also hoping for information which will enable us to expand the range of factors which we monitor and feed our results back to the Environment Agency to help them improve their records.

Last Saturday we had our annual invertebrate monitoring refresher day, organised by Judith and Melvyn from the Calder and Colne Rivers Trust Invertebrate Monitoring Subgroup. As usual it was good to catch up with fellow monitors and find out more about what is going on in our area.

Talks were given by the Environment Agency, Pennine Prospects, The Coal Authority and we were given an overview of a new project concerning Hebden Water which is currently in the planning stages.

Attempting to get a bit of work done in the good weather this morning, I was alerted to this potential bargain.

2.5MW Wind Turbine for sale (Link to pdf file)

We've been on the lookout for something similar to this as we would like to go as off-grid as much as possible. We'd better act quick though as apparently it has made the local news.


So, apparently, this may have been caused by it being too windy. Interestingly, this particular model of turbine (Nordex N90/2500), is marketed as being most suitable for regions with strong winds.

The funny thing is that the winds last night were nowhere near as bad as they can be up on the moor. So it's probably just an unfortunate case of mechanical failure.

We were under the impression that these turbines are braked using the generator, but it looks like we were wrong. Apparently they turn the blades at a full 90 degrees pitch to the wind and there is also a hydraulic disc brake for emergencies.

Whatever the cause, it doesn't look good seeing as the wind farm is only just about 1 Year old.










Disclaimer: Obviously, the PDF file linked to above is for a fictional E-bay listing. Someone suggested to me this morning that the remains of the turbine could go up on everyone's favourite auction site. In the interest of safety. there is a 300m cordon around the damaged turbine, as it should be considered unsafe.

Interestingly, reading an updated article in the Todmorden News, the owner of the site is now given as 'Renewable Energy Systems'. This is yet another name given as the operators of the windfarm. It would be nice to know who actually owns and operates it as the information publicly available seems to be very contradictory. The operators were previously given as Todmorden Moor Windfarm Ltd, at least that is who is registered at Companies House.

We have completed our first year of invertebrate monitoring on Midgelden Brook and have now started on the second.

The results page has been updated and a link which will open in a new window can be found here:-


We are now getting to a position where we can determine if any clear patterns in the invertebrate populations can be found.

Monitoring has also started on Carr and Craggs Moor, right at the top of the hill. Here can be found another badly polluted stretch of water, again from historical mining activities, and another potential location for the Coal Authority to construct a treatment plant.

We will probably create another page for Carr and Craggs Moor as there is a lot of information to digest.

It may seem like we haven't done much in a while as there have not been any updates. We have in fact been extremely busy and it is difficult to think of when we last had a day off.

One of Wal's projects was a new animation that helps illustrate the main processes involved in the pollution of watercourses by 'Ochre Water' from abandoned mineworkings. Click on the link below to take you direct to the page.




 More updates on minewater and invertebrate monitoring are to follow.

The most recent round of surveying for Midgelden Brook was completed this morning and  it can be seen that all 3 sites are in decline. Recent spells of cold weather and heavy rainfall may have had an effect here but we are also keeping a close eye on the adjacent windfarm access track works. You can view the updated results in chart form here:-
