More Nitrogen Deposition

by Ed Tripp, University of Nottingham

Sampling and Sabotage

Nitrogen deposition comes in many forms. It can be diffuse, deposited in rain or from industry, or it can be more localised, from a single farm stocked with cattle or chickens for example. I have already investigated the former with bioassays and modelled nitrogen data. But the latter can be so localised, a matter of hundreds of meters, that it cannot be modelled. Therefore, it has to be measured in the field.


Plant a tree in your community!

Would you like to see more trees in your local park, community centre, playground or churchyard?

The Woodland Trust is offering free tree planting packs to community groups, schools and youth groups who want to improve their local space.

Trees enhance our natural environment in many ways. They improve air quality, attract wildlife, and add colour and interest to our landscape.

Is the future bright for natural history societies?

Are natural history groups struggling or thriving?

Natural history societies play a vital role in protecting and improving our natural environment, but what challenges do they face?

There is a common perception that many natural history societies are suffering from a decline in membership and have difficulty attracting a younger audience.

Lab-Field-Office - Part 3

by Ed Tripp, University of Nottingham

Not all goes as planned.

As I discussed in my last post, by June I had started to collect lichen samples in order to investigate their recovery in heathlands. This process is simple. You go to a heathland site with some pots, scissors and gloves. After eventually finding a patch of lichen, you carefully cut off a small sample and put it in a pot to take back to the lab.


OPAL guides for natural history societies

From guidance on running public events to advice on creating an effective website, OPAL has prepared a number of guides to support the work of your society.

All guides are available to download free from our new societies page.

We’d love to hear your feedback on these guides and develop more over the coming months. Please email your comments and suggestions to

The big freeze!

Brrrrr it's cold here in York! I battled through 5 inches of snow into work this morning and have been welcomed by a very beautiful sight:


Bit of a contrast to last month's post of the same view!

If you live in a part of the country which hasn't yet had snow and are feeling a bit left out, there are lots of snowy photos on iSpot at the moment - I particularly liked this Christmas card robin.
