1. Topic
Baseline Inventory of Invasive Mammal Species
2. Background
There has never been a baseline or quantitative mammalian survey at Hale Pōhaku or in the MKSR. But
we do know that mammals are present; as they have been observed during other surveys. Invasive
mammals include feral cats and dogs, pigs, rats, mongoose, and ungulates; their overall impact on the
alpine and sub-alpine communities are not known.
3. Purpose
Determine a baseline survey of invasive mammalian species to clarify and prioritize future monitoring
and management efforts.
4. Research Objectives
Establish a baseline inventory on invasive mammal species in the MKSR and at Hale Pōhaku to
determine population densities, abundances, distributions, habitat use, dietary and behavioral patterns,
and impacts or threats of mammal presence to the alpine and subalpine regions.
5. Management Applications
Potential uses of a Baseline Inventory of Invasive Mammal Species could: assist with prioritization of
management efforts, guide effective control methods, and understand the impact of mammals on other
native species in the alpine and subalpine ecosystems.
6. Comprehensive Management Plan (and Sub-Plans) Applicability
a. Priority –to be completed
b. NRMP Source – Section 2.2-65, 2.2-66, 2.2-67, 4.1-56, 4.1-57, 4.1-58, 4.1-59
7. Desired Outcomes
 Technical report summarizing project purpose, methods, results, etc.
 Identify management recommendations to address any existing or potential resource impacts.
 Provide a baseline data set suitably documented and formatted for use by other researchers and
management authority.
 Documentation of mammalian trends (new species, seasonality, etc.)
