RSPB Woodland update from DAN September 2013

Despite the cold temperatures earlier in the spring the birds did eventually make use of the nest boxes I installed with many resulting in successful outcomes (i.e. young fledging the nest). It will be interesting to see how things progress in subsequent years and whether any patterns are emerging within the nest box data. The aim of the next stage of the project is to investigate the movement patterns of birds across the City and in particular answer the following research questions: Are the birds that were ringed as pulli in the nest boxes remaining on site or are they dispersing to other sites? What is the general turnover of birds within each of the study sites? Are birds settling at a particular site or are they constantly moving onto other sites due to factors such as predation/competition/resource availability etc? Are there any links between landscape structure, habitat quality and habitat occupancy for the study sites? In order to carry out this stage of the project and therefore to catch birds in flight I would like to carry out a programme of mist netting and bird ringing within the same study sites used for my nest box scheme. Monitoring would involve the temporary installation of mist nets (e.g. super fine 60ft nets attached to metal poles) close to hedgerows, treelines or within rides of vegetation and away from public access routes across each site. The nets would be continuously monitored from a distance to ensure there is no interference from members of the public, predators and to ensure all birds safely removed by experienced bird ringers. Caught birds will be ringed using metal BTO rings and various biometrics taken (e.g. age, sex, weight, wing length, fat and muscle levels) before releasing the birds again. Ringing sessions would take place between the hour of sunrise and midday on a weekly basis and all equipment would be removed from site on completion of the monitoring. Birds’ welfare is of paramount importance and hence all ringing sessions will be supervised by experienced ringers with either A or C permits. Ringing will cease if either bird or ringer welfare are jeopardised. The data obtained would form a significant part of my research and thus I hope you look favourably on my request. Should you have any queries then please do not hesitate to get in touch. I look forward to hearing from you,

Questions
Q1 What do you think are the biggest benefits of teaching and using traditional woodland management techniques in city parks?
A1. The essence of a Ranger’s role is to engage the community at large with the aim of encouraging more people to use parks and green spaces. Therefore a range of themes, topics and activities are employed to meet the broad interests and diverse nature of the public, involving people of all ages, abilities, ethnicities etc. 
The ‘woodland’ theme seems to have universal appeal and is steeped in history, ecology, science, spirituality, mythology and culturally, much more.
So generally we can assume people want to learn something new, make something using natural resources and have an involvement in their local green space, so that a few basic skills, some knowledge and a morsel of understanding related to ecological principles allows people to feel good about themselves and enables them to share these good feelings, acquired skills and gained knowledge with…

Ecotones and Succession = TENSION

The term 'ecotone' cropped up this week as a Tree Officer colleague and I looked at Holders Woods in an exercise to describe the woodland structure, composition and current management.
The word ecotone was coined from a combination of eco(logy) plus -tone, from the Greek tonos or tension – in other words, a place where ecologies are in tension. (Wiki)

Ecotones are generally recognised for ecological richness and a good place to observe the 'tensions' and interactions between certain animals and plants.

A woodland edge for example is often regarded as the richest part of a woodland, especially if the edge is bordered by grassland meadow or water.

The Rea Valley in this regard is a wonderful mix of urban ecosystems and ecotones, and one of my favourite locations is the developing oak woodland at the edge of Holders Woods. Undoubtedly the result of acorn planting Jays, we find oaks ranging from year 1 to year 50, but with a majority of young trees around 10-20 years, sugge…
