Is found in a certain ecosystem due to natural processes such as natural distribution.

native species

Example of native species

koala native from australia

A species that plays a crucial role in maintaining the structure, function, and productivity of an ecosystem

keystone species

Example of keystone species

mangrove trees and starfish

The ability of a population to persist and to avoid extinction

population viability

Is "the capacity of an ecosystem to absorb repeated disturbances or shanks and adapt to change without fundamentally switching to an alternative stable state"

ecological resilience

Include fires, landslides, flooding, windstorms, and insect and pest outbreaks.

disturbances or ecological disturbances

Pioneer species

bare rock lichens small annual plants and lichens grasses and perennials

Intermediate species

grasses, shrubs, and shade-intolerant trees such as pines

Climax community

shade-tolerant trees such as oak and hickory

Happens when parts of a habitat are destroyed, leaving behind smaller unconnected areas.

fragmentation

Is a strategy used in ecosystem management to balance conservation efforts with human activities.

coarse filter/fine filter approach

It's a hierarchical approach that focuses on protecting biodiversity at different scales.

coarse filter/fine filter approach

Managing ecosystems involves dealing with complex, dynamic systems where uncertainty is high.

risk is an adherent aspect of decision making

Uncertainty and complexity

natural variability, human impacts, interconnectedness

Potential negative outcomes

biodiversity loss, ecosystem degradation, social and economic impacts

Is a valuable tool for managing ecosystems in a changing world.

adaptive management

By embracing uncertainty, promoting learning, and adopting to new information, it helps to ensure the long term health and sustainability of ecosystems while balancing conservation with human needs.

adaptive management

Examples of Adaptive Management

forest management fisheries management climate change adaptation

Adaptive management is used to adjust logging practices based on the effects of on forest regeneration, wildlife populations, and water quality.

forest management

Adaptive management is used to set fishing quotas based on the abundance of fish stocks and effects of fishing on the ecosystem.

fisheries management

Adaptive management is used to develop strategies for managing ecosystems in the face of changing climate conditions, such as drought, sea level rise, and extreme weather events.

climate change adaptation

Is a holistic approach to managing natural resources that considers the entire ecosystem, including human interactions, rather than focusing on single issues, species, or services in isolation.

ecosystem-based management (EBM)

Place a crucial role in ecosystem management by safeguarding biodiversity, preserving natural processes, and providing a refuge for threatened species.

protected area

The Seven Environmental Principles

1. everything is connected to everything else. 2. all forms of life are important. 3. everything must go somewhere. 4. ours is a finite earth. 5. nature knows best. 6. nature is beautiful and we are stewards of god's creation. 7. everything changes.

The Seven Environmental Principles in Tagalog

1. ang lahat ng bagay ay magkakaugnay. 2. ang lahat na may buhay ay mahalaga. 3. ang lahat ng bagay ay may patutunguhan. 4. ang kalikasan ay may hangganan. 5. ang kalikasan ng mas nakakaalam. 6. ang kalikasan ay maganda at tayo ay tagapangasiwa ng lahat na nilikha ng diyos. 7. ang lahat ay nagbabago.

The intricate relationships of various elements of the ecosystem bind the components together into one functional unit.

everything is connected to everything else. ang lahat ng bagay ay magkakaugnay.

Human interaction with nature often times alters the ecosystems.

everything is connected to everything else. ang lahat ng bagay ay magkakaugnay.

The waste we improperly dispose of brings about the deterioration of land and water quality.

everything is connected to everything else. ang lahat ng bagay ay magkakaugnay.

All living organisms were created for a purpose in relation to humans, other species on earth and global ecosystem in general.

all forms of life are important. ang lahat na may buhay ay mahalaga.

When a species becomes extinct, it is like removing a piece of a jigsaw puzzle from the web of life.

all forms of life are important. ang lahat na may buhay ay mahalaga.

By products of consumption go back to the environment.

everything must go somewhere. ang lahat ng bagay ay may patutunguhan.

Everything that we throw away—pieces of paper, leftover food, feelings of fruits, plastic wrappers, used containers—have to go somewhere.

everything must go somewhere. ang lahat ng bagay ay may patutunguhan.

Even plants and animals have their own wastes—feces, urine, dead leaves, and branches.

everything must go somewhere. ang lahat ng bagay ay may patutunguhan.

Thus, retrieval, collection and recycling of these materials become necessary so that they do not pollute land and water habitats.

everything must go somewhere. ang lahat ng bagay ay may patutunguhan.

Everything that we need is provided by nature in abundance—food, water, energy, minerals and air.

ours is a finite earth. ang kalikasan ay may hangganan.

However, some resources that we depend upon nowadays are extracted excessively but are slow to replace.

ours is a finite earth. ang kalikasan ay may hangganan.

Nature manifests certain processes that enable it to maintain balance and remain in a state of equilibrium.

nature knows best. ang kalikasan ang mas nakakaalam.

The equilibrium and the ecosystem is maintained, thus if humans intervene, unforeseen negative impacts known as ecological backlash may arise.

nature knows best. Ang kalikasan ng mas nakakaalam.

Floods are often times back lashes of excessive felling of trees.

nature knows best. ang kalikasan ang mas nakakaalam.

Creation free supposes the existence of a Creator.

nature is beautiful and we are stewards of god's creation. ang kalikasan ay maganda at tayo ang tagapangasiwa ng lahat na nilikha ng diyos.

The beautiful nature around us, perfect by itself, has deteriorated due to the negative impacts of human use.

nature as beautiful and we are stewards of god's creation. ang kalikasan ay maganda at tayo ang tagapangasiwa ng lahat na nilikha ng diyos.

This principle suggests how a human-creator relationship is translated in our attitude towards creation.

nature is beautiful and we are stewards of god's creation. ang kalikasan ay maganda at tayo ang tagapangasiwa ng lahat na nilikha ng diyos.

Changes in the biophysical world occur naturally.

everything changes. ang lahat ay nagbabago.

As they say, there is nothing more permanent in this world than change.

everything changes. ang lahat ay nagbabago.

Human-induced alteration such as climate change may cause more massive repercussions.

everything changes. ang lahat ay nagbabago.
