Thank you for your recent query concerning some of the Belfast dendro data, available on line.

I attach your list of queries, annotated. As you will see, mostly this confirms that the data concerned really are missing. In other cases, the annotations clarify ambiguities about sample locations.

Data can be missing for a variety of reasons, including:

1. Some projects were pre-allocated a range of Q-numbers, but only some of the range was needed;

2. Some tree sections were allocated Q-numbers, but never measured;

3. Some projects (e.g. PhD projects) never returned their measurements in an electronic form;

4. Two corrupt files.

I hope this helps. Please let me know if you would like further clarification.
