Today we  had a Meeting with Mike Bailey, the Countryside Council For Wales (CCW) manager of the 2,300 Hectare Dyfi National Nature Reserve (NNR) that sits in the Western end of the Dyfi catchment. This NNR has areas of raised bog, sand dune and estuary within its boarders. Of particular interest for many of the projects at IGES is the raised bog area of the reserve which represents the largest area of such habitat in Wales.

Mike is helping out with several IGES projects ongoing on the raised bog. This is a valuable and fascinating habitat consisting of an area of raised peat sitting some three or four meters above the surrounding landscape. This removes much of the influence of underlying geology and watertable and leads to the development of unique and fragile habitats that have been much reduced in area and quality across Western Europe through peat digging in the past and present.

CCW is putting considerable time and money into the area with land purchase and habitat management aimed at restoring the fringes of the raised bog that have been degraded in the past by conversion to agricultural land and by peat cutting for fuel and horticultural use.

Mike is a case study for the project and is a provider of data that will be accessed by many users at IGES. He may also be able to benefit from students (postgraduates and undergraduates) adding value to some of his data with their own analysis.

The National Nature Reserve is surveyed and monitored in a variety of ways both for CCW and for postgraduate research. This has lead to the formation of a hotspot of data within the Dyfi catchment. Mike’s visit is particularly inspiring in the way he can help to visualise the geospatial data that we have collected . Understanding how records of species at particular x and y coordinates actually translate into understanding the health and nature of a very valuable and visually dramatic landscape really helps to bring this project alive.

The long term needs of ecological habitat management also emphasise the importance of long term data conservation. With some ecological management only showing its results over many years, the ability to safely conserve data and then to be able to rediscover it possibly a generation later will be a tough test for the best practice models for spatial data use and management this project aims to create.

An important part of the data collation for this project is to make sure we know what level of access is allocated to the data. For example some data sets will have sensitive data which would not be for general viewing whilst others will be available to most and students will be able to use it for their research.

We have recently received data set lists from Paul Brewer at IGES and Colin Chapman at WAG. Paul Brewer has given us a list of hydrology data sets as well as LiDAR data and aerial photography for the Dyfi catchment that would be available for all students and academics to access. Some of these data sets have been noted by Jonathan Brownett, MSc student who would like these to help with his thesis research. We have also acquired a list of data that WAG may be able provide. These may contain sensitive data and will have user restrictions. Both Paul Brewer and Colin Chapman should have other data lists available to us at a later date.

Today I met with Jonathan Brownett an MSc student studying at IGES who is hoping to complete a thesis which will investigate land cover change over the Dyfi catchment area using remote sensing. He will use this method to determine the effects of land cover change on the hydrology of the area.

He would find this project very useful in compiling his thesis and already from the list we have compiled he has highlighted a number of data sets that he would like to have access to, to help him complete his thesis. So far there are at least 10 data sets that we have collated that will be useful to him.

After this I made a trip to Ynyslas where the Dyfi Reserve Manager Mike Bailey from CCW was able to locate a number of useful vegetation data sets initially taken from quadrats within the Cors Fochno bog area of the Dyfi Biosphere. This data will be of use to Professor Richard Lucas, academic from IGES and Alisdair Cuningham, PhD student who will be able to use this data for the BIOSOS project which they are working on.

I also received a list of IGES undergraduate proposed thesis titles and so far none of these are focusing on the Dyfi Biosphere. The Dyfi Biosphere is an area which could prove to be a huge resource to such students in terms of research already carried out in this area and the boundless possibilities it poses for more research. The proposed tool/mapping application could be used as a valuable tool for educating these students allowing them to discover the resources it holds.
