Report No. 34, November 2001
INTRODUCTION
The Global Environment Facility (GEF) has provided a PDF Block B grant to South
African National Parks to prepare a full proposal to the GEF for the planning and
establishment of a “greater” Addo Elephant National Park. The concept of the
Greater Addo National Park Initiative (GANP) is described in Kerley & Boshoff 1997.
Systematic conservation planning forms an integral and critical component of the
PDF B project.
The conservation planning exercise requires that the main processes that are
mediated by certain of the larger mammals, and other taxa, as well as the processes
in which some of these animals participate, be identified, and, where possible,
spatially depicted.
This report provides data and information related to the above, and should be read in
conjunction with Boshoff et al. (2001).
Taxonomic order and nomenclature (scientific and common names) of mammal
species referred to in this report follow Skinner & Smithers (1990) (Annex).
Processes
A number of processes are specific to the particular mammal species that drive these
processes. For example, brown and spotted hyaenas are critical for mediating the
process of scavenging.
Processes involving the larger mammals, and the population size targets required to
maintain certain processes, were the subject of two workshops involving scientists
from CSIR-Environmentek, the Terrestrial Ecology Research Unit (TERU) and South
African National Parks (SANP). A “processes” workshop was held at TERU on 11
September 2001, and a “targets” workshop was held, at the same venue, on 19
October 2001. Both workshops were preceded by the drafting of expert-compiled
presentations by TERU scientists. It was agreed at the initial client-consultant,
workshop, held in January 2001, that the focus of the faunal processes component
would be on the medium- to large-sized mammals.
Important mammal population processes have been identified according to three
categories:
1. Species-driven processes
Mammal-mediated processes
By maintaining a population of each mammal species that potentially occurs in the
planning domain, species-driven processes will inherently be captured. A number of
species-driven processes were identified by an expert approach, as were the
mammal species that are considered to drive each of these processes (Table 1).
South African National Parks (SANP) scientists were also consulted as part of the
expert approach.
In general, the omnivores and herbivores mediate a larger number of processes than
do the carnivores. In terms of individual species, the African elephant mediates the
largest number of processes (11 out of a possible 19), followed by the bushpig,
warthog and African buffalo (9 out of 19), and black rhinoceros, Cape mountain
zebra, Burchell’s zebra and hippopotamus (8 out of 19). In this basic analysis, the
prominent role of the megaherbivores is noteworthy, and this emphasises the need
Appendix 5, page 2
Terrestrial Ecology Research Unit, University of Port Elizabeth
Report No. 34, November 2001
for populations of these species to be included in ecologically viable conservation
areas.
In terms of individual processes, nutrient dispersal is the process that is mediated by
the largest number of species (44 out of a possible 44 species), followed by seed
dispersal (32 out of 44 species) and germination facilitation (31 out of 44 species). In
each case, only a single species mediates the processes of geophagy and river bed
biopedturbation. Predation and biopedturbation through hoof action, each with 20 out
of 44 species, are also prominent species-driven processes. It is emphasised that
predation can have a twofold effect on prey species, namely on their population
dynamics and on their behaviour.
It is not practical and feasible to depict spatially the processes listed in Table 1.
These potentially occur throughout all Mammal Habitat Classes (MHCs) in the GANP
planning domain. Some, e.g. herbivory, will be catered for in the vegetation analysis,
on the assumption that appropriate herbivores are maintained. Some processes, e.g
predation and scavenging, will occur across the GANP landscapes as a function of
the presence of the predators and scavengers. This will reflect both the habitat
requirements of the predators and scavengers, as well as the distribution and
abundance of prey species. Thus, in order for these processes to operate, the entire
suite of predators and scavengers, and their prey, is required.
Biopedturbation of river beds by hippopotamus can be spatially depicted by capturing
the sections of hippopotamus habitat that have been identified. Since these are
focused on rivers this will presumably have been captured during the freshwater
processes analysis.
Bird-mediated processes
In general, the extent and distribution of processes that involve birds are too poorly
understood to be spatially depicted, or meaningfully included, in the conservation
planning analysis in the GANP planning domain. We have, however, identified a
number of processes and can only describe them to a limited extent. It must
therefore be assumed, as agreed at the initial client-consultant workshop held in
January 2001, that these processes will be captured by the vegetation and mammal
planning components.
Pollination
Occurs wherever flowering plants occur, i.e. potentially throughout the
planning domain.
Frugivory/seed dispersal
Occurs wherever there are fruiting plants, i.e. potentially throughout
the planning domain (including the dunefield).
Granivory
Potentially occurs throughout the planning domain.
Herbivory
Occurs wherever suitable plant material is available, i.e. potentially
throughout the planning domain.
Predation
Occurs wherever predatory birds and potential prey occurs, i.e.
potentially throughout the planning domain (from fiscal shrikes to
martial eagles)
Scavenging
Occurs wherever carrion becomes available – this is potentially
throughout the planning domain, but cannot be predicted.

Reptile, amphibian and invertebrate-mediated processes
These processes are too poorly understood to be able to depict them spatially in the
conservation planning exercise in the GANP planning domain. It must therefore be
assumed that, as agreed at the initial client-consultant workshop, held in January
2001, processes involving these elements of biodiversity will be captured by
“umbrella” surrogates.
Recommendation: The full GEF project should include a component of research into
the role of the various taxa in ecologically important processes.
2. Population-driven processes
This involves demographic, genetic and evolutionary processes, and each relies on
minimum-sized populations of species to maintain them. It was agreed at the initial
client-consultant, workshop held in January 2001, that the focus of the processes
component will be on the medium- to large-sized mammals. In the case of the GANP
analysis, a key assumption regarding the modelling of mammal population processes
is that the mammals can move freely throughout the entire planning domain for the
proposed park. All species of the medium- to large-sized mammals that potentially
occur in the GANP planning domain participate in these three processes.
In terms of population processes, data must be generated to enable planners to
measure the effectiveness of the proposed “greater” Addo Elephant National Park in
achieving predetermined demographic, genetic and evolutionary targets of mediumto large sized mammals that can potentially occur in the park, to inform decisions
regarding acquisition of additional land, where necessary, to achieve these targets,
and to identify species for which targets can only be met through metapopulation
management.
A consideration for determining minimum area requirements for preserving biological
diversity is that of the estimation of minimum viable populations (MVP) for “target”
species (Wilcox 1982, Soulé 1987). The MVP is a set of specifications concerning
the size and structure of the populations comprising a species that is necessary to
provide a margin of safety from extinction. The MVP for a species can be translated
into the minimum area requirements by determining the amount and type of habitat
that will satisfy the MVP. In view of this, it is necessary for realistic estimates of the
spatial requirements/densities of each the selected species in the GANP planning
domain to be obtained.
The issue of what constitutes demographically, genetically and evolutionary viable
populations is perplexing. These concepts are currently the focus of major debates in
conservation biology and no clear “rules” have emerged yet. We have adopted a
pragmatic approach by suggesting respective figures of 50, 200 and 2000
individuals. The value of these figures is that they represent explicit attempts to
address these issues and can be modified as a better understanding develops. The
figures should not be considered to be acceptable management goals for the
conservation management of the global population of each species, but rather as
goals for populations that could be managed as parts of metapopulations.
50 individuals: This is the population size required to achieve confidence that
demographic processes are taking place. Chance demographic events leading to
extinction will be reduced, but the population will be vulnerable to genetic constraints
(Caughley 1994).
200 individuals: This is considered here as the smallest population required to reduce
inbreeding depression and genetic drift (Lacy 1997). This total population,
Appendix 5, page 4
Terrestrial Ecology Research Unit, University of Port Elizabeth
Report No. 34, November 2001
approximating an effective population of 50 breeding individuals, will vary
considerably between species, depending on sex ratio, mating strategies,
reproductive output and other life history strategies. However, for most of the species
considered here these data are not available and hence this is, again, a first
approximation that can be modified as species and population specific information
becomes available.
2000 individuals: This is a first approximation for an effective population size of 500
breeding individuals, at which it is hypothesised that evolutionary genetic processes
will operate (Lacy 1997). This value may be too low (Lande 1995) and would vary
between species as a function of both the determining of effective population size as
well as the genetic dynamics (evolutionary) characteristics (e.g. mutation rate,
heterozygosity) of the species in question. Adjustment of these figures will therefore
have to await clarification of our understanding of these dynamics.
Population size targets required to maintain population processes in the GANP
planning domain.
An expert approach culminated in the decision that the baseline population size
target for all larger mammal species within the planning domain (i.e. including the 5
km buffer), and using the “intact” transformation category, is 50 individuals. It was
also decided that a retention population size target of 200 individuals will be used for
special species; these are threatened species, as listed in the South African Red
Data Book for Mammals (Smithers 1986) or species for which special conservation
attention is required. For all other species, the retention population size target will be
zero.
Species for which a population target of 2000 individuals can possibly be met by the
proposed park are identified
Species for which the target of 50 individuals could not be met by the proposed park,
and that would have to be conserved through metapopulation management, are
identified. Note that in the long-term it will be necessary to conduct metapopulation
management on all the species.
In the above analysis, the basis for estimating total potential population sizes of the
larger mammals in the GANP planning domain is a series of Mammal Habitat
Classes that in turn are based on a number of Land Classes that were delineated
through vegetation mapping by experts in the field and from satellite imagery (see
Boshoff et al. 2001). Estimates are provided for two park planning domain scenarios:
1) a slightly modified version of the park boundary proposed by Kerley & Boshoff
(1997), and
2) the planning domain in (2) above but with a buffer of approximately 5 km in the
terrestrial zone.
Estimates for (1) to (2) above are provided for two transformation categories:
(a) “Intact” habitat only.
(b) “Restorable” habitat.
(c) “Intact” and “Restorable” areas, together.
The approach and methods followed in generating potential population numbers for
the scenarios listed above are fully described by Boshoff et al. (2001).
Appendix 5, page 5
Terrestrial Ecology Research Unit, University of Port Elizabeth
Report No. 34, November 2001
The estimated potential total population sizes, for each of the planning domain and
transformation scenarios, in relation to the targets mentioned above, are listed in
Table 2, and summarised in Box 1.
Box 1: Summary of the key outcomes in Table 2
Herbivores
The baseline or retention targets are potentially achievable for 21 of the 23 herbivore
species in the “Intact” habitat in the modified Kerley & Boshoff (1997) planning area.
For one species, hippopotamus, the retention target of 200 animals will not be met,
even by the restored full GANP planning domain (i.e. modified Kerley & Boshoff
(1997) area plus a 5 km buffer). The other species, black wildebeest, is marginal
within the GANP domain.
Omnivores/Carnivores
The baseline or retention targets are potentially achievable for only nine of 19
species in “Intact” habitat in the modified Kerley & Boshoff (1997) planning area. If
the “Restorable” habitat is restored, then two of the remaining 10 species (viz.
spotted hyaena and small-spotted cat) will potentially achieve the defined targets.
The baseline or retention targets are potentially achievable for only 11 of 19
omnivore/carnivore species in “Intact” habitat in the modified Kerley & Boshoff (1997)
planning area plus a 5 km buffer. This outcome will not change if the “Restorable”
habitat is restored.
For the remaining two carnivores, namely the Cape clawless otter and the spottednecked otter, potential total population sizes were estimated only for the full planning
domain (i.e. including the 5km buffer). The baseline target for the Cape clawless otter
can potentially be achieved in the modified Kerley & Boshoff (1997) planning area but
this is unlikely to be the case for the spotted-necked otter; the 5 km buffer is required
to meet the baseline target for this species.
Thus, for the carnivores, the retention targets for eight (brown hyaena, cheetah,
leopard, lion, serval, wild dog, honey badger, aardvark) of the 21 species are unlikely
to be achieved, even by the full GANP planning domain (i.e. modified Kerley &
Boshoff (1997) area plus a 5 km buffer), and metapopulation management will have
to be considered for these species.
The species for which potentially viable demographic, genetic and evolutionary
populations could possibly be achieved, by the respective area and transformation
scenarios, can be identified in Table 2.
Discussion
The total estimated abundances for many of the species in Table 2 are not going to
drive the conservation planning process, which will in reality be driven by a few
“umbrella” species.
Species that do not achieve the baseline target (50 individuals) and that could have a
disproportionate influence in determining irreplaceability values for planning units will
have to be treated as special cases in the C-Plan analysis. Given that such species
will mediate, or participate in, certain processes, it is recommended that SANP
should maintain populations in the park, even if this requires an additional investment
of resources.
Appendix 5, page 6

Report No. 34, November 2001
The estimates of the potential population sizes of the carnivores could be further
refined, as part of a separate study, by calculating the degree to which their food
requirements can potentially be met by the herbivore populations.
These
calculations, however, will have to take a number of variables into account, e.g.
which species occur in which habitats, seasonality, movements etc.
3. Spatially-driven processes
The following processes were identified through an expert approach:
 Lateral migration
 Altitudinal migration
 Nomadism
 Dispersal
The process workshop concluded that all of these processes would be satisfied by
including the following:
 an appropriate east-west gradient north of the Zuurberg (as drought refuges);
here it is recommended that two 20 000 ha areas be selected, one in the far west
and one in the far east, joined by a 1 km corridor and with both areas falling
within the modified Kerley & Boshoff (1997) planning domain.
 an appropriate upland-lowland gradient,
 the Zuurberg mountains,
 the dunefield habitat,
 selected N-S and E-W riverine corridors.
