Amcanion cyffredinol

The purpose of the module is to develop students' understanding of silviculture, from its principles in tree biology, to its practical application through forest operations. It aims to: - Consolidate understanding of seed, seedling and tree growth, survival and responses to silvicultural interventions; - Explore the silvicultural systems used in temperate and tropical forests to realise desired future conditions; - Examine the practices used in temperate plantation silviculture.

Cynnwys cwrs

Physiological processes that determine tree growth and survival: Above- & below-ground allocation; root:shoot ratio; Light capture drives productivity; Drought & water-logging; Mechanisms of disease-related death; Response of seedling trees to environmental stimuli. Tree growth and yield. Plant stress and wood quality. Differences/similarities between individual tree, uneven-aged, mixed stands and plantation silviculture: Single-tree selection; Group selection; Seed trees; Shelterwood; Clearfell. Regeneration: Seed and vegetative regeneration; Re-spacing of natural regeneration; Genetic aspects of regeneration. Tending, thinning. Operational aspects of site preparation, planting and establishment. Silviculture for production: Silviculture and timber properties. Forest harvesting and extraction: Appropriate harvesting methods; Mechanised thinning; Organised felling systems; Forest road planning and layout. Environmental effects of forest operations: Sustainability; Legislation.

trothwy

Grade D- to D+ Students have a passing familiarity with the physiological ecology of trees. They can describe some of the silvicultural systems used in temperate or tropical forestry. They will be able to describe some of the methods used for forest inventory and yield regulation and prediction.

da

Grade C- to B+ Students have a good understanding of the physiological ecology of plants, and understand that silvicultural interventions affect plant growth. They can describe many of the silvicultural systems used in temperate and tropical forestry. They will be able to explain several of the ways in which economic methods are used to make forest management decisions, and describe how the methods are applied in different situations.

ardderchog

Grade A- and above Students have an excellent understanding of the physiological ecology of plants, and understand the all the ways in which silvicultural interventions affect the biotic and abiotic factors that control plant growth. They can describe the silvicultural systems used in temperate and tropical forestry, and critically evaluate their relative merits. They will be able to explain in detail the methods used for forest inventory and yield regulation and describe how the methods are applied in different situations, and evaluate their effectiveness.

GWAITH CWRS Remote sensing exercise

You will be required to produce four maps of Treborth forestry management blocks showing:

A. Areas of significant vegetation differences as determined from aerial photography interpretation (RGB and CIR) – 2 maps.
B. Areas of significant differences (canopy structure, tree height) determined from the LiDAR data – 1 map.
C. Any significant features (topographical, hydrological, and archaeological) determined from data derived from the LiDAR data – 1 map.

Your maps will be compiled into a 4-6 page report (determined by the size of your maps). You will need to include coincide detail of your methods and any references you have used. If you attend all the lectures and practical exercises, you will have, all the necessary GIS skills required to complete the report to the highest professional standard.
