Spread Rate
How rapidly the taxon can spread and expand its range in California in the absence of management.
0 = No spread. Taxon remains localized, and often do not persist.
1 = Low rate of spread. Infrequent or inefficient dispersal beyond existing populations. Population sizes remain stable.
3 = Moderate rate of spread. Efficient dispersal occurs locally but population remains within a natural boundary (such as a particular water body or natural area surrounded by human development). Populations expand slowly.
5 = High rate of spread. Numerous opportunities for natural and human-aided dispersal over long distances. Populations can rapidly increase in size.
Spread Amount
How much of California can be infested by the taxon.
0 = Virtually none. There are few suitable habitats or agricultural commodities within the state.
1 = Low amount of spread. The taxon can occupy only a handful of niches (ecological or agricultural) in California, and does not invade any high-value habitats or agricultural commodities.
3 = Moderate amount of spread. The taxon can occupy a significant number of ecotypes in California, which may invade high-value habitats or agricultural commodities.
5 = High amount of spread. The taxon has broad habitat requirements, and can occupy a wide range of ecotypes or ecological niches found in California, and invades high-value habitats or agricultural commodities.
Ecological
Includes damage to ecosystem processes (e.g. geomorphology, hydrology, fire regime, soil or water chemistry, primary productivity) as well as native community composition, structure, interactions, and genetic integrity.
0 = No ecological damage.
1 = Limited ecological damage. Influences ecosystem processes and/or native communities to a minor degree (e.g. has a perceivable but mild influence on soil nutrient availability, reduces the population of one or more native taxon).
3 = Moderate ecological damage. Causes significant disruption of ecosystem processes and/or native communities (e.g. increases sedimentation rates along streams or coasts, reduces areas of open water important to waterfowl, alters water chemistry, alters rate of water retention, reduces ecosystem productivity, substantially reduces the population of one or more native taxon).
5 = Severe ecological damage. Extensive, perhaps irreversible alteration of one or more ecosystem process and/or extensive alteration of native communities (e.g. alters geomorphology, hydrology, or fire frequency, fixes substantial levels of nitrogen in the soil which favors non-native taxon, forms a complete monotype, results in the extirpation of one or more native taxon, significant impacts to one or more native taxon of special concern).
Agricultural
Includes damage to crops, livestock, forestry, horticulture and aquaculture.
0 = No agricultural damage.
1 = Limited agricultural damage. Causes minor impact to agriculture (e.g. somewhat reduced yields, reduced forage for livestock, small increase in susceptibility to fire, some impact to urban agriculture).
3 = Moderate agricultural damage. Causes significant impact to agriculture (e.g. major reduction in yields, loss of livestock, loss of markets by contaminants, compromised genetic integrity of crop taxon, major damage to urban agriculture).

3 = Moderate cultural damage. Causes significant impact to a major cultural resource (e.g. significantly reduced opportunity for a popular recreational activity, disturbance of an historically important landscape, significant damage to landscaping/gardening).
5 = Severe cultural damage. Elimination, possibly irreversibly, of one or more major cultural resources (e.g. destruction of a major tribal collecting area, destruction of a major archaeological site, destruction of a popular recreational activity, major damage to landscaping/gardening).
Health
Includes damage of public health through disease, toxicity, and physical injury.
0 = No health damage.
1 = Limited health damage. Causes low level physical injury (e.g. laceration from thorns, shells of zebra mussel, mildly toxic organisms).
3 = Moderate health damage. Causes potentially significant illness (e.g. provides habitat for a disease vector or organism, moderately toxic organisms).
= Severe health damage. Causes extensive, potentially lethal health impacts. (e.g. pathogens or vectors for a major disease, deathly toxic organisms).
Ecological
Includes ecological services such as pollination, forage, and structure for native species.
0 = No ecological benefit.
1 = Limited ecological benefit. Provides replacement ecological services comparable to those provided by native species it replaces, maintaining the habitat value of invaded areas.
3 = Moderate ecological benefit. Provides additional ecological services, increasing the habitat value of invaded areas.
5 = High ecological benefit. Provides important ecological services to degraded areas so they can then support more complex habitats. Provides a tool that helps in restoration.
Agricultural
Includes benefits to crops, livestock, forestry, horticulture and aquaculture.
0 = No agricultural benefit.
1 = Limited agricultural benefit. Is a minor commodity or supports a minor commodity (e.g. minor horticultural species).
3 = Moderate agricultural benefit. Is a major commodity or supports a major commodity (e.g. pollen source for honeybees, popular horticultural species).
5 = High agricultural benefit. Essential to an entire industry (e.g. high value timber species).
Infrastructure
Includes benefits to roads and bridges, buildings, water conveyance and quality, flood and fire protection, utility rights of way, and other infrastructure.
0 = No infrastructure benefit.
