Population trend
Trend
Honey Badgers are considered to be rare or to exist at low densities across most of their range (Begg et al. 2013). Densities based on night counts have been estimated at 0.1 individual / km² in the Serengeti National Park, Tanzania (Waser 1980) and 0.03 adult / km² in the Kgalagadi Transfrontier Park (KTP) (Begg 2001a). There is unfortunately no density data from the mesic savannahs, such as Kruger National Park (KNP), and it is unknown at this stage as to which areas have higher densities, i.e. KNP vs KTP. Given these density estimates (0.10â0.03 individual / km2), and an estimated 200,000 km2 total AOO across the assessment region, the overall population is between 6,000 and 20,000 individuals, which is likely to be comprised of 3,960â13,200 mature (assuming that 66% of the population is mature, sensu Friedmann & Daly 2004). At the very minimum, the AOO is 37,416 km2 based on confirmed presence in national parks across South Africa (Table 2), which yields a population size of 1,122â3,742 individuals (741â2,470 mature). Thus, the estimated population size ranges from a minimum of 741 to a more likely 13,200 mature individuals. This range encompasses the previous assessment estimate of 4,000 individuals (2,600 mature) using the same area estimate and assuming a 50 km2 home range for breeding pairs (Friedmann & Daly 2004). Further density estimates, both inside and outside protected areas, are required to more systematically estimate population size.
We suspect that the population is stable or increasing given the stable or increasing AOO of the species since the last assessment. Additionally, retaliatory killings from beekeepers have declined since 2001 (Irlich & Davies-Mostert 2009; EWT unpubl. data). Although Honey Badgers may be experiencing local declines outside of protected areas due to accidental persecution or from roads, in some cases the reverse is true. For example, SANParks has found more animals outside of the Agulhas National Park than inside. It is thought that there may be better scavenging opportunities on farms than in the park.
Conservation
Honey Badgers are found in many protected areas throughout the assessment region (Table 2). In the North West Province alone, Honey Badgers occur in 7â8 protected areas (confirmation required for the 8th protected area), within a total area of 1,390â1,700 km2 (Power 2014).
However, Honey Badgers are persecuted by apiculturists for the damage caused to commercial honey production. The South African beekeeping industry contributes an estimated R3.2 billion to South Africaâs agricultural economy through pollination alone, with an additional R100 million through honey and bee products and creates direct employment for about 3,000 people and indirectly for 300,000 to 500,000 people (Begg 2001b; Allsopp et al. 2008; NAMC 2008). Begg (2001b) and Begg and Begg (2002) showed that hive damage could be reduced from 24% to 1% with the help of hive-protection methods; for example, by securing beehives 1 m or more above the ground on a stand or trestle, thereby minimizing conflicts between Honey Badgers and apiculturists. Begg (2001b) also highlighted that it was economically more viable for beekeepers to be âBadger Friendlyâ.
Thus, the BadgerâBeekeeper Extension Programme (BBEP) was established in 2002 to educate beekeepers on effective beehive protection measures and Honey Badger conservation, as well as public awareness on the topic (Isham et al. 2005). As part of the project, a âBadger Friendly Labelâ (BFL) was developed. The purpose of this project is to assist South African beekeepers in preventing damage by Honey Badgers to beehives by the use of initiatives that prevent Honey Badgers from damaging hives â a non-lethal control method. This prevents the use of other lethal control methods such as poison, gin traps and killer traps that have a negative impact on Honey Badger and other carnivore populations. This is a long-term solution that secures valuable habitat for Honey Badger populations on farmland in South Africa. Hence, the label was a voluntary incentive to be used only by beekeepers that effectively protected their beehives and thus removed the need to harm Honey Badgers. Furthermore, this label was used to indicate to the public which honey products were produced by Badger Friendly practices and thus provided leverage for consumers to put pressure on the beekeeping industry to change their ways. The labels were sold at a small cost to beekeepers that had signed a declaration copy and which after an inspection of their apiary sites were accredited with Badger Friendly Statusâ (Isham et al. 2005). The BFL Project has been running since 2003, and it has become routine for many South African citizens to purchase such labelled products.
Isham et al. (2005) found that of the protection methods implemented, approximately 90% of the beekeepers protecting their hives made use of methods that raised the hives off the ground, while only about 10% used onâground protection methods. It was confirmed that a hive in good condition, securely strapped to a stand of at least 1 m (Photo 3) reduced the chance of badger access significantly.
During a critical assessment of the BFL project (Irlich & Davies-Mostert 2009), a total of 46 records of hive damage caused by badgers, making up 26 Quarter Degree Grid (QDGs) squares, were collected. This is significantly fewer when compared to a total of 179 records of hive damage in 70 QDGs collected by Begg (2001b). According to the beekeepers, badgers are not the most severe threat to honey production anymore. Instead, vandalism and theft are the most severe threats, as they indirectly decrease the number of available sites where beekeepers can keep their beehives. The threat of direct persecution for beehive depredation is thus inferred to have lessened over the past decade. Reports of beehive damage have declined between 2001 and 2009, by an estimated 66% through the work of conservationists in promoting hive protection methods (Begg 2001b; Irlich & Davies-Mostert 2009). Of the 62 beekeepers audited by Irlich and Davies-Mostert (2009), only 16 sustained hive damage from Honey Badgers, while 46 did not sustain any damage since protecting their hives despite high badger activity in the regions. Similarly, while 64% of beekeepers listed badgers as the top threat to productivity in Beggâs (2001b) report, only 12% did so in 2009. Of those who listed badgers as a threat, 85% said that the impact of these mustelids was negligible compared to only 33% in 2001 (Begg 2001b; Irlich & Davies-Mostert 2009). During the course of this assessment (2008â2009) only a single report was received of a badger being killed by beekeepers in Mpumalanga (Irlich & Davies-Mostert 2009). Thus, the overall consensus was that the problem of Honey Badgers raiding beehives is decreasing in intensity or, at worst, staying constant, with no beekeepers mentioning that the conflict was increasing in intensity or frequency of hive damage. This is likely due to the effective protection methods being implemented by beekeepers across the country (Irlich & Davies-Mostert 2009). It is possible that a few beekeepers are still killing badgers without reporting these cases. However, the beekeeping community is a small one and beekeepers are very aware of what fellow beekeepers are doing, and therefore a majority of incidences are likely to have been reported.
More recently, a 2016 Badger Friendly Audit was conducted by D. van der Merwe who is the Carnivore Conflict Mitigation Officer of the Endangered Wildlife Trust. The audits took place during March and April 2016 at a number of beekeepersâ properties in Gauteng, Northern Cape, Eastern Cape, Western Cape and Limpopo provinces. A total of 27 beekeepers were audited and 26 of them complied with the criteria in order to obtain the BFL (EWT unpubl. data). The project has been a success in that the majority of the beekeepers who were audited and who suffer damage due to Honey Badgers are still protecting their hives effectively against badgers, even if the beekeepers are not making use of the BFL. In areas of high conflict between beekeepers and Honey Badgers it is financially more beneficial to protect hives rather than persecute Honey Badgers. According to the lack of reports of badgers being persecuted by beekeepers, it can thus be interpreted that the project has continued to be effective in mitigating badger killing by beekeepers since 2009. Many of the beekeepers are using their own methods to prevent damage, which includes putting the hives into large cages and modifying the standard raised platforms. The beekeepers in the Western Cape and Limpopo seem to be having the largest amount of damage, while some of the honey farmers in the Northern Cape audited have never seen or have never had damage from Honey Badgers at all. One of the most interesting findings during this audit was the apparition and increase of badgerâbeekeeper conflict in the Oudtshoorn area. Over the last three years, all beekeepers in the area have had to protect their hives as it was becoming financially unviable to farm with bees (EWT unpubl. data). Overall, the 2016 audit confirms that the BFL project has decreased the number of Honey Badgers being killed by beekeepers as a result of effective hive protection methods, and can thus be considered a genuine conservation success.
However, more work needs to be done to increase consumer awareness of Badger Friendly products and thus to incentivise beekeepers to continue with the project. In 2009, only 2.8% of consumers said that their first choice was whether the honey displayed a Badger Friendly label and the number of stickers sold to retailers declined from 2005 to 2008 (Irlich & Davies-Mostert 2009). Clearly, more work needs to be done to raise the public profile of the label and increase consumer buy-in. The retail of Badger Friendly honey is an intervention similar to âgreen labellingâ that holds sway at the level of the consumer. To increase the number of consumers buying Badger Friendly honey, additional intensive consumer awareness should be undertaken. It would be beneficial to involve members of the public nationally in using consumer power to support the initiative, as well as contributing their data on Honey Badger sightings and become engaged with badger conservation in general. This could be carried out in conjunction with more public awareness and social marketing on badgers and the BFL project.
Recommendations for land managers and practitioners:
- Monitoring should be established to measure local subpopulation trends. For example, North West Province intends to monitor subpopulations of this species through camera-trapping (see Power 2014).
- Continue to encourage beehive protection methods. The average cost of beehive damage is R950, while beekeepers protecting their hives against badgers can expect to pay anywhere in the range of R1 up to R650 per hive (Isham et al. 2005). Beekeepers must be informed via the media and popular magazines (for example, Farmers Weekly) of the most reliable and cost-effective measures for protecting beehives.
- All apiaries situated within biosphere reserves or along the borders of protected areas must be adequately protected, as conflict with Honey Badgers is inevitable. This should be mandatory.
Research priorities:
- Intensive research into the current distribution of Honey Badgers, together with possible estimates of their abundance (both inside and outside of protected areas) is required to successfully address distributional changes in the future. To carry out such an investigation will prove to be time-consuming, and thus citizen science schemes (for example, through social media) should be established to aid with data collection.
- Quantifying long-term population trends in different biomes and land-use areas.
- Trends in the numbers of animals killed by farmers.
- Trends in the numbers of animals accidentally killed in traps intended for other target species.
- Home range size for different vegetation types (particularly Fynbos, Karoo and Renosterveld types) so as to be able to evaluate space requirements for viable populations at the local scale.
A wealth of information has been obtained from one particular ecosystem, the arid Kalahari savannahs (see Mills 1997; Begg 2001a; Begg et al. 2003a,b, 2005a,b, 2016a,b, in press), in the western part of South Africa. The following biogeographical areas need to be focussed on, should there be such a further need:
- Spatial and population ecology in mesic savannah ecosystems.
- Spatial and population ecology in Fynbos ecosystems.
Encouraged citizen actions:
- Report sightings on virtual museum platforms (for example, iSpot and MammalMAP). Priority areas include southern KwaZulu-Natal and the far Eastern Cape Province. Camera-trappers should strategically deploy their camera traps in pursuit of this species and upload their records to bona fide data repositories.
- Only purchase Badger Friendly honey. Contact the Endangered Wildlife Trust (ewt@ewt.org.za) for further information.
