Native Grass Gazette: NatiVeg – Helpful Tool or Curious Tchotchke?

I hate answers that begin with “it depends.” That usually means you are about to be inundated with tons of detailed, probably useless information which ultimately ends up with no clear answer to your question.

So, is NatiVeg a helpful tool or just a curious tchotchke? As much as it pains me to say this, it depends. How are you going to use it and what do you expect to get out of it?

First, for those not familiar, NatiVeg is a mobile website (https://www.quailcount.org/NatiVeg)  developed by NBCI to aid planners in selecting the correct native vegetation for their geographic location (limited to the 25 NBCI states) for their intended use. Released publically for comment on Nov. 16, 2016, NatiVeg can be used either as a desktop application or with a smartphone with GPS capability. An internet connection is required.

Many land planners dealing with working lands have limited knowledge of native vegetation, let alone its adaptability to a specific site or for specific purposes. NatiVeg was developed to provide planners with no or limited knowledge of native vegetation a tool for identifying native vegetation adapted to their selected location for their selected use. The target audience is persons providing technical assistance to landowners and/or landowners with the primary objective of incorporating native vegetation into their working lands.

NatiVeg uses Plant Hardiness Zones (PHZ) and Major Land Resource Areas (MLRA) as spatial components for search criteria of a database of Natural Resource Conservation Service Plant Material Center (NRCS-PMC) releases. NatiVeg returns a list of species known to be adapted to your selected geographic location. Herein lies the answer to the question of whether NatiVeg is helpful or a curious tchotchke.

Plant materials in the NRCS-PMC database have been through a process to document a variety of criteria, depending upon the intent of the release. In a majority of cases seed is commercially available or foundation seed is available for commercial increase, many of the releases have been planted in growing trials and their area of adaptation is documented, cultivars and selections have been made for desirable characteristics and there are some areas where local germplasm releases have been made with no selection criteria. (Both of those last two attributes are either good or bad depending upon your intended use and location) However, there are some limitations to the NRCS-PMC database; there are a limited number of releases (306 in the NBCI modified database) compared to a list of species that would have historically occurred for a location and there is skewed geographic distribution of native species releases, leaving limited choices for selected areas within the NBCI states.

MLRA’s are large geographic areas that are geographically associated land resource units based upon the dominant physical characteristics using physiology, geology, climate, water, soils, biological resources and land use, and they are thousands of acres in size. Obviously, there is variability within these areas, so though you may be in an MLRA where little bluestem is adapted, your specific location may be mesic or wet mesic and not suitable for little bluestem. For that reason, it is also important to consult the “Details” section of each species in NatiVeg to determine its appropriateness for the site. Information about collection location, comments or site adaptations can provide additional information to aid in decision making. If you still have questions or would like help there is a link to the state agency to help you find local assistance.

What about our non-target audience? Since the launch of NatiVeg I have received several comments from ecologists  wishing the application were more specific in relation to local ecosystems and vegetation communities. Fair comments, though those changes wouldn’t particularly serve our target audience any better. Remember a few lines above where I was listing the attributes of using the NRCS-PMC database; “There are some areas where local germplasm releases have been made with no selection criteria?” In some areas within the NBCI states there have been ecotype collections made and seed increases done. South Texas and Iowa/Missouri are two examples. Ecologists working in those regions will find plant materials suitable for restorations. Unfortunately, there is limited species availability and our database returns still don’t give a “big picture” list of species endemic to the location.

We are working on ideas to address this and determine if we even need to. It appears, based upon feedback, there is some need/desire for this type of product. At this point we don’t know if we will develop an entirely new product or work to expand NatiVeg, but we are examining options using NatureServe data or NRCS Ecological Site Description data. There may be others and we’ll examine all options.

Knowing some of the limitations of the database and spatial criteria, and understanding how to use additional resources to deal with those limitations, NatiVeg should be a helpful tool for our target audience … and in some instances our non-target audience. If you’re expecting a list of species endemic to your local ecosystem, then NatiVeg is probably a curious tchotchke.

To answer the question,” Is NatiVeg a helpful tool or curious tchotchke?”  It depends.
