Sampling

Sampling involved establishing the fundamental relationships between work to be undertaken by WP5 and other workpackages. Initial discussions were held with other workpackages about collection of shared data to minimise overlap of work. Protocols for long-term field and laboratory experiments were designed.

These included:

i) Experiments on recruitment of seedlings under field conditions,
ii) Seed burial and recovery experiments,
iii) Studies of the size and composition of soil seed banks under field conditions, conducted by soil core sampling,
iv) Experiments on seed dispersal under field conditions, and measurement of seed terminal velocities under controlled laboratory conditions,
v) Comparative studies of germination responses to temperature of seeds collected from different countries of origin including all of the countries participating in TRANSPLANT.

Protocols for experimental work were finalised and distributed to other work packages. A novel design was developed for the equipment used to measure seed terminal velocities. Components were ordered, assembled and tested exhaustively prior to being used for measurement of seed dispersal characteristics and modelling of patterns of seed distribution around source plants and populations. Extensive fieldwork was undertaken to identify field sites appropriate for experiments to be conducted under WP5, and for experiments undertaken on behalf of WP2 and WP3. In addition, the field sites chosen were characterised using physical and edaphic measurements.

Seeds were collected from all participating WPs for terminal velocity trials, for the UK-based seed burial experiment, and for experiments undertaken as part of WP2. The legal implications, and customs regulations for sending soil, seeds and plant material from partner countries participating in TRANSPLANT, and from other EU and non-EU countries, were examined. Appropriate protocols were designed for processing and packaging seeds for shipment from different countries without causing damage to the seeds or alteration of their physical or architectural properties.
