LTMN North Walney NNR - target habitat sand dune (LTMNB42)

The target habitat for this site is sand dune. We also monitor saltmarsh.

An introduction to the NNR can be found in the NNR leaflet attached below.

Data collected:

Weather Air Quality Vegetation Soil Birds Butterflies
2013 onwards 201520152014 onwards2007 – 2010

R = Representative data

Representative data will be used from a Met Office station on Walney Island as North Walney NNR is within the climate envelope of this weather station.

Data available to download:

• Weather Data can be found on the Met Office Weather Observation Website.

• The vegetation data goes through a full QA process and is available to download below.

Update May 2020: all LTMN vegetation surveys (no. 80 surveys, spanning 2010 – 2019) have been transferred to a new template to provide improvements and consistency, and are now fully Quality Assured and republished.

Please note that the permanent plot numbers and locations should be consistent between surveys, for each site. At the time of survey, for any previously installed feno markers that could not be found, a new feno marker was installed at the same GPS coordinates and the plot number changed from e.g. ‘2’ to ‘2a’. High accuracy GPS has been used across two thirds of sites and will be used across the remainder within the next two-three years.

Please also note that for some sites (Bure Marshes, Dark Peak, East Dartmoor Woods & Heaths, Lullington Heath, Mottey Meadows and North Walney), there were adaptations to plot numbering between years and that the most recent plot numbers have now been back-tracked to the earlier surveys to allow comparability, as explained on the front page of the relevant data spreadsheets. For any queries, please contact the Long Term Monitoring Network team for a Master Plot Tracker.

• Soil data for this site can be found on our LTMN Soils protocol page.

• Butterfly data can be found below – also see UKBMS website.

We are preparing the bird and land management data and will be publishing it in due course. For any specific queries about our data please get in touch with the LTMN mailbox:
