ecosystem restoration
60
refers to the process of managing or assisting the recovery of an ecosystem that has been degraded, damaged or destroyed as a means of sustaining ecosystem resilience and conserving biodiversity
ecological restoration
61
two approaches can be combined that any meaningful restoration treatment has to address both the structure and ecological processes within the concerned ecosystem.
ecological restoration
62
seeks to quickly return the structure of a given ecosystem to what it was before it was disturbed
structural approach
63
seeks to return core ecological processes to the role they had before disturbance took place
process approach
64
is characterized by a decline or loss of biodiversity or ecosystem functions
degradation
65
deals with the crisis of maintaining the genes, species, communities, and ecosystems that make up the earth’s biodiversity
conservation
66
investigates the preservation of the biologic and genetic diversity of animal and plant species which is effectively promoted by restoring natural habitats
conservation
67
rooted in population biology which is generally organized at the genetic level, looking at specific species populations
conservation
68
may be viewed as a sub-component of biodiversity conservation program since it primarily deals with restoration or revitalization of the species’ natural habitat which is an important locus of biodiversity protection
restoration
69
organized at the community level, looking at specific ecosystems
restpratopm
70
which is intended for the maintenance and subsequent utilization of genetic diversity
genetic based approach
71
- which is directed to species diversity;
species based approach
72
which looks into ecosystem diversity.
ecosystem based appraoch
73
usually done in genetic reserve to maintain suitable ecological conditions and the conservation needs of target species
conservation method
74
ensures the availability of genetic material of the species that has undergone genetic erosion from demographic fluctuations, environmental
conservation method
75
conservation effort extended to significant species (endangered, endemic, umbrella species, biodiversity indicator species, etc.)
species based approach
76
approach can provide specific, measurable targets (e.g. species persistence, increased abundance, and distribution) to evaluate success of the conservation action
species based approach
77
integrated comprehensive strategy projected to protect, preserve, and utilize ecological resources, or communities sustainably
ecosystem based approach
78
primarily uses adaptive management to deal with the complex and dynamic nature of ecosystem
ecosystem based approach
79
may be classified either in-situ or ex-situ conservation
conservation technique
80
is a conservation of genetic resources in natural populations of plant or animal species within their natural habitats.
in-situ conservation approach
81
The approach is generally done to enable biodiversity in maintaining itself within the context of the ecosystem in which it has been found. Such requires conservation of the components of the natural system (populations, species, communities and biophysical systems) as well as the ecological and evolutionary processes occurring within that system
in-situ conservation approach
82
aimed at the environmental areas where a target species developed its distinctive properties (genetic reserve conservation
in-situ conservation approach
83
environmental area heavily modified by human activity
on-farm conservation
84
ecosystem conservation which leads to the establishment of a more comprehensive technique called protected area management system.
natural habitat
85
is a geographically defined area that is designated or regulated and managed to achieve specific conservation objectives
protected area
86
area may be set aside for the protection of biological diversity, and of natural and associated cultural resources and is managed through legal or other effective means
protected area
87
provide a multiple flow of benefits to humans as they are established to protect a wide variety of features such as: characteristic or unique ecosystem, special species of interest, value, rarity or under threat, tourism
protected area
88
This approach has been widely used as a conservation tool in order to maintain a representative sample of unaltered species and eco-systems for the future, and to limit the potential for environmental degradation through human mismanagement of resources.
protected area management system
89
Generally smaller areas where the preservation of important natural values with minimum human disturbance is emphasized. Protected areas managed mainly for science or wilderness protection. what category
category I
90

framework that is consistent with the IUCN global categories
National Integrated Protected Areas System (NIPAS)
102
s a conservation of biodiversity for the maintenance of natural variation of genes, individual or population of species outside their natural habitats. It prioritizes plant and animal species that are critically endangered and/or extinct in the wild.
ex-situ conservation approach
103
The collective purpose of the approach is to conserve either whole or parts of the target specimen
ex-situ conservation approach
104
Conservation by building biorepository that stores and preserves genetic material of crop varieties or domestic animals. This is primarily done by freezing cuttings from plants, or sperm and eggs from animals until further need.
gene banks
105
Conservation by housing whole, target plant or animal specimens for specific purpose which includes: public exhibitions, tourism, education, scientific, and conservation possible breeding and/or subsequent reintroduction into the wild.
botanical garden and zoos
106
These are storage facilities for the conservation of germplasm contained in the seeds of the target wild plants, agricultural crops, and forest species. This is primarily done by preserving dried seeds at a very low temperature.
seed banks
107
Conservation that saves plant material for short, medium and long-term time in a small place and in a controlled condition. In-vitro conservation is dependent on plant cell, tissue and organ culture techniques.
in-vitro conservation
108
do not provide natural condition where the elements of organic evolution and long term ecological processes can operate.
ex-situ facilities
109
must only complement rather than replace in-situ conservation measures since the best way to conserve species is to protect them in their natural habitats.
ex-situ conservation
110
measures include measures (e.g. soil microbial processes, evolutionary processes, specific ecosystems such as coral reefs or species with highly specialized needs).
ex-situ conservation
111
may be used on some or all of the population, when in-situ conservation is too difficult, or impossible. It is only until methods are available to discern easily which of the millions of species and varieties will have economic value, that ex-situ conservation may be used as a means conservation of biodiversity
ex-situ conservation
112
was the preferred biodiversity conservation approach over ex-situ conservation
in-situ conservation
113
Measures include (genetic reserve, on-farm, and ecosystem conservation) are perceived to be more holistic in their approach and allow the conservation of processes or habitats
