Early detection is crucial in protecting native plants and animals from severe damage caused by invasive species. The longer it takes to respond to an invasive species, the more money and time must be spent restoring and protecting the ecosystem. Severe economic effects can be prevented by alerting local growers of an invasive species and how to manage it without profit loss. If management techniques can be developed rapidly, the response is much more effective. There are 7 steps to making Early Detection, Rapid Response method successful. Click on each of the steps to the right for a definition/summary, and methodology.
A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced data and information. GIS allows one to input, integrate, analyze, model, interpret, and visualize spatial data in ways that reveal relationships, patterns, and trends in the form of maps, reports, and charts. GIS helps answer questions, solve problems, and even market new research ideas by observing spatial data in a way that is easily understood and shared.
T.I.S.I. is in the early stages of acquiring and integrating up-to-date, highest spatial resolution available, state-wide (Texas), digital geo-spatial data sets (i.e., ecological systems, geology, topography, hydrology, land cover, protected areas, etc.) into a GIS that will be appropriate for the study and management of invasive species. These maps will initially be used to display point data gathered by citizen scientists and researchers that report the location of existing and new communities of invasive species. The primary objective is to eventually be able to supply the scientific and greater user community with geospatial data that are suitable for input to ecological niche models. These models describe environmental conditions under which invasive species should be able to maintain populations. As input, these models use a set of point locations where invasive species are known to exist (i.e., in their originating country/region) and a set of corresponding geographic map layers representing the associated environmental parameters that might represent a species preference to establish. The end result is an invasive species prediction model and/or map. These predictive maps are particularly useful to field teams that are responsible for monitoring the spread of invasive species and conducting associated early response actions.

The identification and validation component of E.D.R.R. represents a public interface to a group of tools that will assist users in correctly identifying suspected invasive species. It serves as a filter to help minimize false reporting.

This component of E.D.R.R. provides an interface to a suite of tools and resources for reporting invasive species sightings or identification of suspected invasive species. Some tools may overlap with those listed in the identification and verification components.
Reporting is necessary for Rapid Response. Learn how you can report invasive species here.
The expert verification component of E.D.R.R. provides support through the verification of submitted invasive species. Our team of experts are highly trained taxonomists that specialize in the identification of suspected invasive species.
When an invasive species has been surveyed, it is necessary to review its occurrence, allowing researchers to determine what facilitates its growth in a new environment and what allows it to continue inhabiting the other parts of the United States.
Soon we will be featuring our database and curated specimens housed at the T.I.S.I. facilities. These databases serve as repositories for verified reports of biological invaders.
This component of the E.D.R.R. provides access to monitoring, modeling, and forecasting tools to perform rapid assessment of the threat of new biological invaders. It also serves as a repository for response efforts.
T.I.S.I. houses several research scientists, taxonomic experts, and field technicians equipped to rapidly assess a suspected biological invader.
The planning component of E.D.R.R. includes activities and resources involved in preparing to address and manage invasive species. These resources include management plans, training courses, recommended practices, site conservations plans, and standards & guidelines.
APHIS has created very detailed control plans for various invasive animals, plants, and microbial pests. These control plans help entities like T.I.S.I. with rapid response on a state-wide level. Also, these plans can be utilized by citizens to control the invasive species they find on their property.
The rapid response component of E.D.R.R. provides access to resources that support the process of notifying appropriate authorities and first responders to new biological invasions, using expertise databases and jurisdictional and authority information; and provides technical support for optimal response action.
