Allan Strand and Sean Hoban published a new paper today in Biological
Conservation on *designing effective ex situ seed sampling protocols*.  In
the paper, the authors use simulations that account for a species
reproductive biology and other aspects of a sampling expedition.  The main
message is that a collector can integrate species' biology into the
planning of collections in a quantitative manner, and can thereby can *help
the collection to reach set targets for diversity*.  For example the
authors show that sample sizes for a selfing, low dispersal species may
need to be about 5 times larger than high dispersal, self-incompatible
species.  Collections from small spatial coverage of a population (such as
along a roadside) will also need many more seeds (2 to 10 times) than
collections that randomly sample the whole population.  This work adds to a
rich body of literature on seed sampling and, along with other recent work,
should help invigorate discussions and development of new solutions to this
long-standing challenge.

Hoban can send a PDF, contact shoban at utk.edu).  Please share this with
colleagues and friends in the plant conservation community!

There is of course much work to be done to continue to develop new
protocols.  Sean Hoban will continue this area of work, with many exciting
questions, some of which are summarized at the end of the article.  If you
are interested to know more or to work on particular species or challenges,
