Ecology and Wildlife Risk Assessment

 

This analysis of case studies from Los Alamos National Laboratory, and the case study to

 

predict the effects of pesticides on aquatic systems and the waterfowl that uses them. Comparing

 

the two processes of these case studies, along with analysis of the assessments. Describing the

 

case study on the effects of pesticides in aquatic ecosystem, the risk assessment correlated to

 

observed field studies and evaluate the importance of this type of correlation in general for all

 

risk assessment efforts. Breaking down the ecological and social values in the assessments.

 

Try to establish a value for the components in each case and how the risk assessment was

 

determined.

 

The process of defining ecological value in Los Alamos National Laboratory (LANL)

 

from section 19.5 took an approach to take a structured process to break down the value of the

 

different species that are located at LANL. This was done to ensure that all relevant valued

 

resources was used to come up with the endpoints, and provide the proper documentation to

 

form a structured that was based on the resources. This process known as the general assessment

 

endpoints (GAE) helped eliminate data that was not needed and helped provide the means of

 

having data that was needed to follow through with the assessment, along with the values for

 

each potential ecosystem that is based on potential exposure to the environmental stressors.

 

The comparison of the two assessments take a different approach as the endpoints are

 

staggering in the LANL case as the amount of species possess many possibilities to establish

 

the relevant value of the endpoints that are needed to complete the assessment. By utilizing just

 

the values that the stakeholders suggested in case study Los Alamos National Laboratory, the

 

assessors focused on the immediate values on certain species the all as a hole eliminated the

 

possibility of the lesser values in the case study. The workgroups (aquatic) began their attempts

 

Ecology and Wildlife Risk Assessment 3

 

by explaining the main problem that is addressed within a pesticide risk assessment and it then

 

began to define the many sources involving uncertainty for assessing exposure and effects. This

 

technique of probabilistic assessment has helped in the reanalysis of the case study of pesticides

 

on aquatic systems. This allowed assessors to look closer at the issues at hand relating to the

 

organisms.

 

The case from chapter 22 is based on a case study on how pesticides affect the impact

 

on ecology. This risk assessment helps explain probabilistic assessment, and it then broke down

 

the probability of researching the possibility of direct harm in duck populations. The time frame

 

that the pesticides are used to reduce grasshopper population is around the same time that the

 

ducks are breeding, rear young and lay eggs. This is the concern for the use of pesticides in

 

these pothole regions across America and Canada. This case study provides a reanalysis of the

 

wildlife in the pothole regions. The use of probabilistic methods is entered into the process to

 

characterize variability’s and the uncertainties of the effects on aquatic macro invertebrates

 

from the pesticides that are released to control agricultural pest control. The assessment shows

 

in the data that the results of the analysis are a way to relate the uncertainties of mortality in the

 

ecosystem. Along with the damage that is done with the food source for the ducks.

 

The pesticides case study applied a different risk assessment framework and hypothesizes

 

to improve the final analysis process to cover all the grounds and bring attention the uncertainties

 

of the damage that is being inflicted onto the water fowl and ducklings that are in the region

 

during the time of treatments. The exposure levels are at a high during the treatment process.

 

Thus setting up a risk assessment frame work allows the assessor to take the uncertainties to

 

another level to determine the effects on the contamination faze of the treatment time frame.

 

A framework was developed and it incorporated the characteristics of agricultural landscapes,

 

Ecology and Wildlife Risk Assessment 4

 

aquatic ecosystems, and chemicals that interact to influence exposure. From this particular

 

framework, the workgroups came up with a tiered system that works for the risk assessment

 

process where the assessment carries on from a determining assessment to probabilistic

 

assessments of increasing complexity. Each individual tier includes several analytical and

 

experimental options that reduce uncertainty and provide more complete descriptions of the

 

aquatic environment (Environmental Protection Agency, 2012).

 

The risk assessment was to use the field data to include the uncertainties that eliminates

 

any more future concerns with affecting the species during this process, along with the reduction

 

of the mortality rate among the ducklings. The breakdown of the uncertainties was used in order

 

to predict probability and magnitude of any adverse effects to the non-target terrestrial and

 

aquatic species that results from introducing into the environment, and probabilistic analysis

 

used in the assessment provides quantification towards the uncertainties in the risk estimate.

 

The risk assessment of the complex exposure to the pesticides provides methods to estimate

 

the probability and impacts resulting from exposure, in this approach. In al it sheds light on the

 

case study that certain elements and processes need to be changed in all phases of general risk

 

assessment.

 

The ecological and social values of concern in the first case study Los Alamos National

 

Laboratory is the different array of possibilities that are presented in the amount of species that

 

are involved, establishing a structured assessment to eliminate the less valued resources. The

 

process is used to establish the most valued resources to help in setting management goals and

 

endpoints to complete the assessment. The ecological and social values of concern in the case

 

study on pesticide contamination are that there are so many aspects on how to eliminate the less

 

informative data to complete the case study. The social value is to combine the stakeholders

 

Ecology and Wildlife Risk Assessment 5

 

concerns and incorporate assessment managers and assessors input to implement valued

 

endpoints to reach a conclusion and game plan to eliminate the risk that are on hand. The social

 

values of these cases, points to preserving the regions that are treated, eliminating the harm to

 

all organisms in the ecosystem that is contaminated by the pesticides. The social values are that

 

these regions house many species and food sources, this assessment breaks down the damage

 

that is being done and the damages that are effecting the ducks in the region. The ponds are

 

watersheds that protect the habitats of many organism, thus having a healthy environment is

 

needed to produce a healthy ecosystem. The ecological view is to preserve the regions from

 

harm, allowing the pesticides to be used in a manner that the organisms are not affected by them.

 

The value of the ecological components in the Los Alamos National Laboratory

 

case study would be the principle values the functional integrity, biodiversity, and the energy

 

dynamics and nutrient contents. By doing so the strongest of the species are chosen to be valued

 

endpoints, so positive results come from the assessment. The trade off would be instilling

 

sensitive species that could be extinct with the decision to use as a value endpoint when they are

 

too sensitive to give a positive result. The value of the ecological components in the effects of

 

pesticides on aquatic systems is that the uncertainties of the valued resources are eliminated and

 

evaluated to have the best valued endpoint to work with in the case study. The tradeoffs relating

 

to the wildlife and development is that the species if not grasshoppers that are at risk then it is

 

the ducks that are present during treatment process. The contamination will alter either one of

 

these species value in the ecosystem. The risk assessment in these cases is determined by

 

compiling the concerns of all parties involved and eliminating the less valued uncertainties, to

 

have valued data to come up with goals to meet all of the concerns. Risk assessment is known as

 

a process where scientific information is used in order to address any possible environmental

 

Ecology and Wildlife Risk Assessment 6

 

risks associated with pesticide use. A Good regulatory decision relys on an understanding of the

 

strengths and weaknesses of the specific risk assessment, sound professional judgment in

 

drawing conclusions from compiled data, and documented scientific research. The

 

Environmental Protection Agency states that risk assessments should successfully and clearly

 

identify the most important facts along any assumptions deemed necessary to accurately evaluate

 

the pesticide (Environmental Protection Agency, 2012).

 

The probabilistic analysis process can be improved in the chapter 22 case study by more

 

research of the effects on the organisms involved, along with going in another direction on

 

controlling the grasshopper’s presence in these pothole regions. During a process of elimination

 

of what harms of being caused by the toxin, the analysis can be altered to focus on the main risk

 

factors and once those issues are addressed then one can run another assessment and conclusion

 

as you eliminate even more sensitive data from the finale analyst. These points along helps

 

explain the importance of the Ecology and Wildlife Assessment.

 

The conclusion to the analysis of the case study helps break the process of implementing

 

different type of risk assessments for different issues on hand. The need to eliminate the more

 

sensitive values and collection of data is the key to performing an assessment to help the

 

environment. Finding the valued endpoints and compelling enough data to eliminate the more

 

sensitive resources, to come up with a positive and accurate decision in the long run.
