Jake,<br><br>I have used QGIS extensively for inventory, management planning, timber sales, and similar forestry work. I think you will find it can do everything you need it to. While ArcMap is traditionally used in our business, the low (free) cost of QGIS presses it far past that of the commercial products. <br>
<br>In regards to Forestry, I have yet to find an application where GRASS would be more productive than QGIS. There are, however, times I have had to use another free program called uDIG to handle various Coordinate Reference System conversions that QGIS seems to have trouble with. That said, I think these oddities are isolated to a small number of specific geographic areas. <br>
<br>In regards to Acres. There are options where you can turn your default units to "feet". While this will not show information in "acres", it will give it to you in sq ft or sq miles, either of which can easily be converted for those of us familiar with the standard parcel/property land measurements. <br>
<br>I also encourage you to use the "open-layers" plugin. This will give you several options for automatically incorporating aerial photography. However, I have found that sometimes the "positioning" is a little off. So use it with caution if you're attempting to outline stands or forest property. I find myself using the regularly available 1998 ortho photos when precision is critical. <br>
<br>The forestry tool-kit, is being developed more for certification and
tropical applications than traditional forest management in the sense you and I practice. If there is
the interest, I would be willing to work with other individuals to
develop a plugin more tailored to on-the-ground resource managers. I think this is something currently lacking from the open-source community that would more greatly enhance QGIS' adoption within our field.<br clear="all">

<br>
Deleting a feature is not the same as deleting a field, and requires a<br>
feature to be selected.<br>
Deleting a field from the attribute table window is I think only possible<br>
with QGIS master and gdal 1.9<br>
