Honaunau is 27,000 ac and here we focus on the best part of the area which is about 10,500 ac in what has been a Forest Reserve since the begin of the 20th century. In 2004 we started the process… Refer to 10 principles & their criteria and move to next slide
Forest may / not contain HCVF, but you do have to look around to confirm whether it exists. Confirmation is achieved by testing values 1 – 6, if any of them are present, either in terms of biodiversity, ecosystems ,or culture, then HCVF is present on the property and must be managed as such.
Original designation was based on spatial data including soils, vegetation cover, endangered species habitat, and conservation district zoning. The most consistent spatial data were protected areas versus not—HCVF was defined to coincide with the highest level of legal conservation protection. We had not yet collected field data across the entire forest to accurately guide us
Criterion (I), which involves integrated values (4, 5, 6), is top priority for the landowner, which aligns client interests in potential HCVF with FSC requirements. Criterion (II) are additional reasons to designate HCVF / reasons for eligibility under FSC rules.
FSC 3rd party certifying agency required a clearer definition of HCVF and some evidence showing that the selected area was valuable. In response, we developed a formula to test whether areas truly qualified as HCVF. Example, a value may be met however is it truly high-value in context.
A next step toward identifying HCVF areas was comparison of native versus non-native vegetation cover from existing datasets. For example, areas where non-native shrubs are dominant would not qualify for HCVF status, suggesting that the South-Central section is a candidate. (West section is un-measured, but full of guava).
Of the data that we did have here is a presentation of some figures, the green is native
To conform to FSC regulations we needed to collect more data to support these preliminary findings so that there was a near continuous distribution of plots, i.e. data
It is not the case that these areas are completely free from invasive species--to the contrary, invasive plants are nearly ubiquitous across the forest. The areas characterized by a high contingent of native species are quality forests because the area occupied by native species outweighs the area occupied by non-natives by at least 300% (three to one).
Whereas previous weed management activities in Hōnaunau Forest were conducted with a good degree of prior planning based on field observations and the original weed assessment report, this past work was not informed by a clear valuation of forest quality that has arisen as a result of forest management presence and multiple FSC audits. As a consequence, weed control resources were focused on preventing spread of existing and potential weeds rather than the health of the remaining intact forest.
The main treatment series recommended for this plan is to control approximately 160 acres annually in Suppression and Eradication FMU, including HCVF and 40 acres of roadside buffers at an average cost of $225 per acre based on previous control efforts by FSIA single weed control entry is usually insufficient to guarantee long-term control with constant dispersal of propagules, so sweep operations are recommended to ensure lasting success. $130 /ac Eradication, $100 /ac Suppression, and $75 /ac roadside (two-year return interval
A central core zone in the mid-elevation forest contains clearly superior native ecosystems that merit HCVF status. This conclusion derives from a variety of factors, including conformance to HCVF values 1, 2, 4, and 6, spatial analysis of quantitative vegetation data, and field validation

Invasive species management in Hōnaunau Forest should result in forests
dominated by native species in which sustained exclusion of invasive
species can be accomplished with comparatively little effort
