Module Content & Assessment

Indicative Content
Tree identification
Identification of a large number of tree and shrub species by their outline shape, their foliage, flower and fruit characteristics and by winter twigs. Evaluation of species selection for specific sites.
Tree planting and establishment tasks
Ensuring acquired tree stock is of sufficiently high quality for purpose; this means methods such as including sufficient establishment preparation, thorough checking for the absence of pest and diseases, delivery with plant passports in the case of foreign stock. Suitable site preparation including tree pits, methods for planting and their early establishment, including staking, guying, bracing and anchoring systems as appropriate. The control of weeds by chemical and non chemical means. Techniques for protection from climate, animals and vandalism for newly planted trees. Woodland and forestry planting methods, including mound planting. Transplanting techniques and establishment of large trees.
The Maintenance of Trees
Typical maintenance tasks for trees, above and below ground, including tree surgery and pruning. Diagnosis of ill health on trees including decay, pests, diseases and disorders. The identification of hazardous trees. Identification of damage both above and below ground level and assessment of its consequences for the overall health of effected trees. Damage assessment via visual tree assessment (VTA) using both biological and mechanical methods. Other instruments and techniques associated with assessment.
Trees in Urban areas
The impact of various types of excavation on tree root systems. The effects of site development on trees and their growth and development. Methods and measures to minimise disruption of trees and to protect them during and after the development of sites. Particular methods for transplanting semi-mature trees.
Tree Surveying
Methodology and purpose of surveying trees. Structure of a tree survey report and required information to be included. The typical personnel involved in carrying out tree surveys in a range of contexts. The appraisal of tree survey report for its content and recommendations.
Woodlands and forests
A brief outline of the history of arboriculture. The significance and primary utility of forests and woodland areas. Analysis and primary features of the ecology of woodland areas, both pristine and as influenced by human settlement. The necessity for and reasons behind surveying woodland areas.
