Questions and Answers

Please review the following questions received and their corresponding answers.

Q1. Is the contractor expected to treat all invasive species or just the ones listed in the contract?

A1. Only the species specified in the Statement of Work must be removed.

Q2. What percent coverage of area treated would be required to fulfill the contract requirements?

A2. Please see section 5E, Performance Measurement, of the updated statement of work.

Q3. Are georeferenced .pdf maps of treament areas available?

A3. Yes, these have been attached to this ammendment.

Q4. Are shape files for the treatment area polygons available?

A4. Yes, shape files may be requested by contacting the TPOC, Doug Manning at doug_manning@nps.gov by 5PM EDT 6/28. Allow 48 hours for response.

Q5. How should the percentages provided for each treatment area be interpreted? Should 19.6 acres estimated to at approximately 2/3 invasive species be interpreted as 13.06 acres containing invasive species at 100% density?

A5. That number is an estimated density of presence but not overall cover. For example, there may be trees growing with Japanese knotweed below them. The trees are likely native and provide some amount of cover but the knotweed does as well. We are just looking at the overall cover of invasive plants excluding the presence of native plants that may be present as well.

Q6. Is it safe to assume that all areas with perhaps the exception of kudzu areas are spot treatment of the acreage areas?

A6. For the most part, yes. There will be some areas that have dense infestations of Japanese knotweed at Nuttallburg.

Q7. Is it acceptable that work begin later in the summer, i.e. August/September?

A7. Project start is flexible provided work can be completed within the established Period of Performance.
