Northern spotted owl (Strix occidentalis caurina) recovery strategy: chapter 16

13. Socio-economic Considerations

The SORT recognizes that the RENEW Recovery Manual (ROMAN 2003) does not require a detailed socio-economic analysis to be incorporated in the recovery strategy, as the assessment of recovery feasibility is to be based entirely on biological, not economical issues. Rather, the socio-economic analyses are to be conducted during, and incorporated into, the recovery action plans after the biological and technical feasibility of recovery has been determined in the recovery strategy.  However, due to the significance of the potential costs and impacts of recovery actions, or lack thereof, for this species in British Columbia, it was felt prudent to incorporate a strategic-level description of the scale, scope and location of the impacts.  It will be equally important, but likely more difficult, to assess the value of the benefits of recovery, both in economic terms and in terms of not losing a native species.  The following sections are an attempt to outline some of the aspects of socio-economic costs and benefits that will apply to recovery of the Spotted Owl in British Columbia These will be used to guide more detailed socio-economic analysis as the SORT moves on to identifying and assessing potential recovery actions.

 

A)  COSTS

The costs of recovery can be broken into various categories including the costs of increased habitat protection, the costs of establishing and implementing population augmentation activities, the costs for activities targeted at improving survival and recruitment, and the costs associated with conducting needed inventory and research. 

Increased Habitat Protection

Habitat protection is a key issue throughout the species’ range.  The Spotted Owl has no chance of recovery if sufficient suitable habitat is not conserved in the appropriate spatial distribution throughout its range.  Some habitat within its range is considered non-recoverable.  This is largely limited to urban and rural habitat in the Lower Mainland, much of which is under private or municipal ownership and cannot feasibly be converted to suitable Spotted Owl habitat.  One major exception to this is the Capilano, Seymour and Coquitlam watersheds of the Greater Vancouver Regional District.  These are large areas of forested habitat north of the City of Vancouver that are managed to protect the Greater Vancouver water supply.  They are already included within the existing Spotted Owl Management Plan (SOMP) and do not require additional protection.  

As the Spotted Owl requires large areas of old-growth forest habitat for breeding, foraging and dispersal, it is anticipated that the biggest impact of increased habitat protection may be in the forest sector, including the British Columbia Timber Sales Program, through impacts on the timber harvesting land base (THLB) and timber supply.  Potential THLB impacts will be limited to the parts of the Squamish, Chilliwack and Cascade Forest Districts (FDs) within the species’ range.  It is important to note that the impacts to the forest sector, in terms of total additional hectares set aside, may not be as great as anticipated.  There are already 363,000 ha managed for Spotted Owls within the Squamish and Chilliwack FDs under the existing SOMP.  There is no habitat set aside in the Lillooet area of the Cascades FD, which currently holds several active territories.  However, the draft Land and Resource Management Plan (LRMP) for the Lillooet area does contain an allotment of habitat to be dedicated to Spotted Owl management that is sufficient to incorporate most of these active territories.  Theoretically, if the LRMP habitat budget is added to what already exists in SOMP, depending on the amount of overlap that can be incorporated through clustering of adjacent territories, there may not be a need to add much more total area to have enough territory to meet the recovery strategy’s goal of 250 adults owls (assuming this is roughly equal to 125 pairs/territories).  However, the existing network of conservation areas is quite fragmented, and the final Habitat Action Plan may require the spatial arrangement of these areas be reconfigured, including the establishment of connectivity corridors to allow for better dispersal between them, and to the U.S. populations to the south.  Ongoing modeling efforts should help determine how best to arrange the conservation areas on the landscape and how best to accomplish this over time.  These modeling efforts could also assist to capture and compare timber impacts of different landscape scenarios. The need for some additional protection is likely in the short term to ensure protection of survival habitat (areas that contain known occupied sites), but other changes could be incorporated/recruited over a longer time frame.

Other development activities that may be impacted to a lesser extent include mining operations, hydro developments (e.g., powerlines, dams), recreational developments (e.g., ski hill expansions), and urban/rural developments (e.g., roads, housing, agricultural expansion).  In addition, much of the range of the Spotted Owl is under some form of First Nations land claim and some Indian Reserves may overlap suitable habitat.  It is unknown how resolution of First Nations interests may impact on habitat protection measures

Population Augmentation

Although habitat protection is required to enable recovery, population augmentation could have a significant impact on the level of recovery attained and the rate at which it occurs.  Given the extremely low population estimates currently available for British Columbia, some level of population augmentation may be necessary to prevent extirpation in the short term.  Augmentation programs could be applied anywhere in the species range, but would be focused most on areas where populations appear to have “winked out”, or where single birds are believed to be persevering alone with little chance of finding a mate.  

As stated earlier in this report, three approaches to augmentation are considered feasible.  These three approaches each have there own costs.  A brief summary of the scope of the items to be considered for socio-economic assessment include:

In addition, before proceeding with these approaches, strategies that assess available methodologies, past experience, people and materials required, and chances of success should be prepared.  People involved in these programs may include SORT members, MoE staff, and contractors.  Partnerships would need to be made with private facilities for breeding and housing birds.  Some of these actions would require long term commitments to facilities, staff and funding.

Increased Survival

Another approach is to try to ensure survival of existing birds and increase the rate of recovery of the population is to attempt to increase their survival in the wild.  The two methods suggested in the recovery strategy include predator/competitor control and winter feeding.  These approaches could be applied to existing wild birds wherever they are known to exist, and/or to any areas where owls have been translocated or introduced.

Predator/competitor control may prove controversial, but is technically feasible, and may be justifiable in areas where considerable effort and cost has already been spent on introductions and translocations.  It would likely be neither economically feasible, nor socially acceptable, to embark on a long-term control program at all territories throughout the Spotted Owl’s range.  Costs associated with this activity would be those associated with hiring people capable and willing to locate and destroy predatory and competing species from designated Spotted Owl areas. 

Winter feeding of juveniles to help them survive their first winter (known to be the period of highest mortality) would require locating young birds and applying transmitters to them in order to be able to track them through the winter to occasionally provide them with food. Costs would include staff/contractor time, costs of radio-transmitters, helicopter rental, and costs of acquiring suitable food items.  If successful, this could prove to be a most cost-effective approach.

Research/Inventory

Research and inventory are needed to ensure that the recovery actions recommended are based on the best science available and have the greatest likelihood of attaining the recovery goal.  Modeling is required to help determine the best spatial arrangement of habitat on the landscape and what demographic factors are the highest priorities to work on.  Research will help us to better understand the relationships between the owls, their habitat, their prey and their competitors which will result in better management approaches to address these issues. Inventory is needed to find and monitor the owls and their nests sites for habitat protection, population augmentation, and increased survival approaches identified above, as well as to evaluate the success of recovery efforts over time. The greater funding available for research and inventory, the better the science based results will be.   Appendix 2 contains a preliminary list of research topics.  Research and inventory could occur anywhere throughout the owl’s range and would involve SORT members, government and industry scientists, academia and contractors.  Partnerships, creation of a Spotted Owl recovery fund, and use of existing funding agencies could help share the costs.

 

B)  BENEFITS

It will likely be much more difficult to assess the economic value and benefits of recovering the Spotted Owl than it will be to assess the costs.  This is partly because some of the benefits entail reducing the likelihood that a potential punitive action could be taken, and it is very difficult to determine the value of something not occurring.  It is also partly because it is very difficult to put an economic value on an esoteric concept such as preventing extirpation of a species, though some attempts have been made in this regard.  Nonetheless, it is entirely possible that the long term benefits of recovery of a species could outweigh the short term costs.  Some of the benefits that need to be considered include:
