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.

A quick hello from your newest member (Steve Walsh) I now have my feet under the desk at Aberystwyth and look forward to working with you all. I will try and keep up regular blogs on developments….

I had a meeting with Jonathan Brownett yesterday and got some very useful insights into the use of spatial data from the coal face …….Below is a brief summary of Jonathan’s section of the project’s case study.

Jonathan Brownett – IGES MSc student 

Project 

 Jonathan is looking at land cover change in the Dyfi Catchment over an 8 year period using a mixture of data from LANDSAT 7 and field parcel data (LPIS) from the Welsh Government. He has also made use of the Digimap service to access OS MasterMap data and elevation and shape file data accessed from within from IGES. 

Jonathan is then relating this data to the relatively new Land Cover Classification System (LCCS) which uses pre defined classifiers that can be applied to a level of detail suitable for a particular project. With this method he should be able to track changes in 20 or so categories of vegetation, bare land and water covered areas. 

Combined with some confirmation of actual ground cover species Jonathan should then be able to describe some of the major land cover changes  that have happened in the Dyfi catchment (very similar in extent to the Dyfi Biosphere area). 

He is well underway with his work and should have his data analysed buy the end of July and should receive some expert help in using LCCS from Lucile who will be visiting the Department from France and will be bringing her expertise in carrying out LCCS ground survey to the Dyfi Biosphere area. 

Relevant experience for the IGIBS case study 

In several ways Jonathan is a very useful case study as he has recently come from a Conservation BSc and has experienced GIS and Remote Sensing courses and the functioning of an SDI in two academic departments. With his MSc thesis he is now   discovering the intricacies of accessing data from external agencies and discovering the wealth of data held by individual researchers with their own approaches to metadata creation. He is also being forward thinking and has suggested that some of his data might be suitable to use for undergraduate teaching so suggested that he will discuss the best way to make available the research data he has generated with his supervisors.

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.
