Have you thought of using GPS systems instead of transects? GPS is
accurate 
to .01 cm or less for lat/long and a bit less for altitude.
And requires little time to set up. You can then measure
each individual plant rather quickly. Some GPS have data storage
capabilities
as well, or you can rig it up with a laptop, then you can cover a lot of
ground quickly. As a futher refinement, add a digital camera which feeds 
into the laptop to take photos of each plant, then put all this 
in your database. All this can give you a lot more data 
of higher quality that can be sampled, recorded, and studied
in a faster time with better accuracy. The Army should have GPS systems 
you can use, or they can spring for a quality commercial system with 
data interface into a laptop and the digital camera setup. You can put
an Oracle 8 database on a Windows NT laptop which will store and 
correlate all kinds of data including spatial and image data. You
can then export this data to a main storage system. 

I work with this stuff every day and it is very doable.
