ESTABLISHMENT OF NEW PLANT POPULATIONS

Methods to establish new plant populations are different from establishing vertebrate or animal populations. Animals can move from one place to another in search of food or moisture conditions. In plants the seeds are dispersed to the other sites through wind, water and animals or by conservation biologists activity.

When a seed is planted on a site it is unable to move even if a suitable site exists at few meters distance. The immediate small suitable site is necessary in case when environmental conditions become harsh e.g. the weather is too hot, too wet, too dry or too shady. In these conditions the seeds either don't germinate or plants die. Plants are vulnerable to attacks by insects, pests and fungi. Fire also disturb the seeds establishment.

Considerations while reintroduction of Plants

• Careful site selection should be taken into account otherwise plants will not be able to survive or flower.
• Those factors should be identified that cause the decline in plants species.
• Management techniques should be developed to manage the introduce and native species.

Some plant populations fail to establish when seeds are planted at the sites even sites were found suitable for them. In a case seeds of 6 annual plants species were planted in 48 suitable sites. After 2 years the plant population persisted on 5 sites and after 6 years population persisted on only 1 site. At these successful sites the population size of species of plants increased to 10,000 and it spread to 30 m around margins of marshy pond.

In another case seeds of 35 perennial herbs species were sown at 173 sites. No seedling was observed at 167 sites out of 173 sites. No individuals were seen at 32 out of 35 species.

The problem arise while sowing the seeds is that the species did not mimic the natural process exactly. To overcome these problems new techniques were introduced such as:

• Fencing to exclude animals
• Removal of existing vegetation
• Plant nurse plants in arid regions
• Adding mineral nutrients

Keys to Success

The keys to success are as follows:

• using as many sites as possible
• use as many seeds and adult plants as possible
• reintroducing species year after year at many sites
• careful monitoring of seedlings and adults
  

Case Study

The large flowered fiddleneck is an annual plant belonging from northern California. It has not a wide range. These species decline due to livestock grazing and fire suppression. Reintroduction of these fiddleneck was done with careful considerations such as management of grass specific herbicides and burning. This was first implemented in experiment than it was applied to natural population resulting in increase in plant population.

CONSIDERATIONS FOR SUCCESSFUL PROGRAMS

Establishment of new populations is quite difficult and expensive and it requires long term and serious commitments. The programs to capture, raise and monitor the species such as condor, peregrine falcon, ferrets millions of dollars are required and millions of year work is needed. When species are long lived they required that much time to take care of the program. Emotional public issues were raised while decision making of reintroduction of grizzly bears, grey wolf programs, black footed ferrets and California condor.

Criticism

Criticism regarding this reintroduction programs raised were:

• Waste of Money
• Unnecessary
• Intrusive
• Poorly run
• Unethical

Answers to these Questions

The answers to these questions is simple that not every endangered specie is suited for reintroduction program. A well designed and well run reintroduction program proves to be best option for the endangered species that are at the verge of extinction. It is very important to explain the goals of programs to the local people. Public acceptance should be involved. Local community should be addressed with the need of these programs rather than the enforcement by laws and regulations. 

Genetic component should be taken into account in reintroduction programs. Captive bred animals lose their genetic variability. The captive animals grown in captivity from generations leads to gene frequency changes such as in Pacific Salmon. Careful selection of animals should be done against inbreeding depression and to produce more genetically diverse populations.

Soft Release

"Animals need special care and attention during and after the release of species. This approach is known as soft release."

Animals have to be fed and sheltered at release point. They are initially kept in cages at release point so that they are familiar of the area and than they are gradually released into the wild. 

Hard Release

"Release of animals from captivity to wild without any initial subsistence such as food supplementation is known as hard release."

This results in the dispersion of groups from the protected areas and it proves to be a failed effort.

Interventions are necessary for the survival of species especially in droughts or low food abundance conditions. Outbreaks of diseases and pests must be monitored. Impact of human activities such as agriculture and farming must be seen. 

Reintroduction programs have gained educational value. The efforts to reintroduce and preserve the Golden Lion Temarins in Bazil has become a rallying point for protecting the last fragments of Atlantic coastal forests.

Captive bred Arabian Oryx has become a national symbol and became the employment source for people of Bedouins.

Monitoring Programs

These programs are important in determining whether the reintroduction programs are achieving their stated goals. Monitoring elements are:

Determining the animals that are released are survived or not? 

Establishing breeding population than seeing if this population is increasing over time and geographical range.

A Case Study

Red Wolves Reintroduction

Red Wolves were reintroduced in Alligator river National Wildlife Refuge in northeastern north California. 42 captive bred species were introduced. Survival observed was 50 % after 3 years and 23 pups were produced. Animals established here survived by hunting on raccoons and eating carrion. This program was proved to be successful effort.

BEHAVIORS OF RELEASED ANIMALS WHILE INTRODUCTION AND REINTRODUCTION PROGRAMS

If we want to make reintroduction and introduction programs successful than behaviors of released animals should be addressed while releasing the animals in any habitat.

Social Animals Learning: When social animals such as mammals and birds grow in wild, they learn about their environment from their members of community especially from their partners. They learn how to interact with other members of the population. They learn how to search for food, how to get that and consume that food. 

For Carnivores such as lions and wild dogs, hunting techniques are complex and these require a teamwork.

Herbivores such as Hornbills and Gibbons have to learn the seasonal migration patterns to obtain the variety of food by covering a large area to make them alive. They are also taught in family groups how to capture  and find food. Many species perform some cues or rituals to attract the mate. 

ANIMALS RAISED IN CAPTIVITY

Animals that are raised in captivity (in separate preserved area species are grown with special conditions provision) they are restricted to a cage or pen and no exploration to other animals in wild is required. They have no need to learn how to search food or how to compete with other species for food. They are not learned how to interact with other species. They are given food on schedule in their cages. Social behavior of species are greatly effected by captivity because they are grown alone in unnatural grouping e.g. single gender or same age groups). Social skills are not developed in that individuals such as find food, sense, danger finding mate partners, raise young ones. 

TRAINING FOR BUILDING BEHAVIORAL SKILLS 

For overcoming this problem captive bred mammals and birds should be trained before and after releasing into the environment. They must learn how to avoid predators, find food, interact with other species. Captive animals are learnt how to fear from potential predators by frightening by a dummy predator. Captive techniques should be built. 

Examples

Captive Chimps for example are learnt how to use twigs to feed on termites or how to build nests in captivity.

Red Wolves are learnt how to kill live prey.

SOCIAL INTERACTIONS

Social interactions are one of the difficult behavior being adopted in species. One successful attempt used is to pair the captive bred individual with the wild animals and released together. Wild animals acted as instructors.

For example, Golden Lion Temarin wild specie is introduced with captive bred Golden Lion Temarin specie. Captive bred specie learn from wild ones.

Humans also mimic as predators to captive bred individuals so  to adapt them from predators. 

For Example, Condor hatchlings are not adapted to learn behavior of their relative wild species. They are fed with condor puppets and kept from sight of visitors so that they could recognize their own species and could differentiate their species from humans.

Some captive bred species when released in wild they mate with wild species and make a social group. They learned from them. But it is not a successful practice for birds. Wild birds during migration became a cause of high mortality rate of captive bred bald ibis.

ESTABLISHING NEW POPULATIONS TO CONSERVE ENDANGERED SPECIES

INTRODUCTION

Many endangered species are at verge of extinction, many conservation biologists are developing strategies or approaches to save these species. These approaches involve increasing size of existing population and establishing new wild or semi wild populations of rare species. These approaches allow the species living in captivity or in small isolated populations. The populations that are widely spread are less destroyed by events such as earthquakes, hurricanes, disease, epidemics). By increasing the population the chances of extinction reduces.

Establishment of new populations decline the original wild species of that area. For example a brown snake specie was introduced in Pacific Island where birds species already existed. Birds species were eliminated by the predation of snake. This was not a good reestablishment practice. Either snake species should be introduced into other island or birds species nests should be protected from snakes or birds species should be introduces into other islands. 

APPROACHES FOR ESTABLISHING NEW POPULATIONS

Three approaches are used to establish the new populations of animals and plants. These are as follows:

• Reintroduction Program
• Augmentation Program
• Introduction Program

REINTRODUCTION PROGRAM

The reintroduction involves the releasing captive bred and wild collected animals in the areas that are in their historic range and where no species no longer existed. 

The main objective of reintroduction program is to provide new environment in original environment to species. For example reintroduction of grey wolves in Yellowstone National Park with the aim  to maintain the equilibrium of predators and herbivores existed in that habitat already. The individuals were released near the site where their ancestors lived and adapted to genetic modification or elsewhere within the range of species where new protected habitat is produced.

Reintroduction can also be termed as reestablishment, restoration or translocation. 

AUGMENTATION PROGRAM

It deals with releasing the individuals in the existing population to increase the size of population and to enhance gene pool. The individuals that are released may be captive bred or wild collected.

INTRODUCTION PROGRAM

It involves introducing the animals and plants to the areas that are outside their historic range. This approach is used in the case when existing habitat is destroyed to the level where species could no longer survive there and reintroduction program could not be possible there. These also may be captive bred or wild collected.

Care must be taken while introducing the species so that species does not damage the existing ecosystem or harm the population. Care must be taken so that introduced species could not acquire the diseases while in captivity. Species may also adapt genetically to its new environment.

WHAT IS CLEANER PRODUCTION?

INTRODUCTION

Different approaches are used to deal with environmental degradation problems since over long time industrialization was started in different nations. The approaches such as to avoid the problem; to dilute the pollutants so that to reduce the impacts of pollutants; treat the pollution after it happens (end of pipe solution); prevent the pollution at source by cleaner production techniques were used. It is clear from the approaches that from over long time shift has been taken place from avoid to prevent that would enhance the economic investments, and improve the environment. This is the primary goal of cleaner production.

"Cleaner production is defined as the adoption of integrated preventive environmental strategies applied to processes, products and services in order to reduce the impacts, risk and harm to the environment and humans." 

Cleaner Production in terms of Production Processes

Cleaner Production in terms of production includes the care taken during the production processes such as preservation of raw materials, prohibition of toxic raw materials use and declining the amounts of waste production and toxicity.

Cleaner Production in terms of Product Processes

Cleaner Production in terms of product involves the care taken in product development and design e.g. reduction of harmful impacts in the whole life cycle of product development from raw materials mining to disposal of wastes. 

Cleaner Production in terms of Services Processes

During the delivery of services environmental parameters should be taken into account.

Difference between Pollution Control and Cleaner production

The basic difference between pollution control and cleaner production is of time. Pollution control is done after the pollution occurs means end of pipe treatment, react and than treat. While cleaner production deals with prevention, prevention of pollution at source by using cleaner production techniques. It is said that prevention is better than cure. Cleaner production reduce or can completely eliminate the pollution control strategy. Cleaner production is applied already in fisheries, agriculture, tourism, transportation, hospitals, energy systems etc.

CLEANER PRODUCTION PRINCIPLES

• Aim is to reduce the environmental and social impacts
• Reduce the raw materials use and energy inputs
• Reduce the toxicity of emissions and waste production
• Use of system analysis approach
• Production process is divided into inputs, activities and outputs
• It use the waste management hierarchy that is:
• Avoidance is better than reduction, reduction is better than reuse, disposal is on least priority. 

CLEANER PRODUCTION TECHNIQUES

Techniques used are:

Technological Advances

New equipments or new technologies are used such as heat exchangers used to capture heat from refrigerators.

Design Specifications

It is applied in the planning stage of development process

Housekeeping

Proper maintenance and proper workplace practices is one of better practice in clean production.

Process Optimization

Existing process could be optimized in order to reduce resource consumption patterns.

Raw material Substitution

Hazardous raw materials could be replaced with efficient raw materials.

BENEFITS OF CLEANER PRODUCTION

• Reduction of environmental impacts and risks.
• Improvement in production efficiencies
• Decline in energy use and production of waste
• Decrease in operating cost

RISKS AND BARRIERS OF CLEANER PRODUCTION

• Hinderence by management to introduce change
• High upfront cost with long paybacks
• Some measures are not applicable to short buisness

ENVIRONMENTAL ETHICS

Environmental Ethics assume that moral norms govern the

human behavior towards natural world.

Many ethics regarding the environment were presented by environmentalists. These are as follows:

UNIVERSALISTS 

• Plato and Kant presented this ethic. The concept describes that fundamental ethics are universal and  unchanging. 
• The rules of right and wrong are valid without concerning the interests, desires and attitude.
• God has created these rules or these are revealed for any reason and knowledge.

RELATIVISTS

• This ethic was of Sophists. It claims that moral principles are relative to any particular person, society or condition.
• Ethical values are context based.
• Friedrich Nietzsche's said that there are no facts only interpretations.

NIHILISTS

This ethic was given by Schopenhauer. Very dark view was given by him. He said the World has no sense at all. Life is dark. To exist on earth unceasing struggle is required. Its just like eat or to be eaten. There is no such thing that is good in life. Life is about suffering, pain, uncertainty and despair.

LAND ETHIC

• Land Ethic was presented by Aldo Leopold. According to this ethic, Land is not considered as mere object or dead thing to be owned as property. 
• Land life is a living thing. It should be viewed as living organism...
• According to this, preserve all the forms of life on the earth to maintain the stability of world. When small changes occur in the system, the system self sustained it.
• Leopold made a conclusion that a thing is right when it maintains the integrity and stability of biotic community  otherwise it is wrong.

ENVIRONMENTAL STEWARDSHIP

• This ethic represents the views that there should be care of the place and to manage it properly.
• We are partners of nature rather than masters of it.
• There should be collaboration with nature to sustain it and make it a better place.
• According to Islamic Scholar Dr. AbuBakar Ahmad Bagader " everything in this universe has the value. God gives the humans stewardship on the earth. And man is a manager on earth not a proprietor, a beneficiary not a disposer; Man should care the earth and use it as trustee.

ECOFEMINISM

• It is a pluralistic (Freedom of Thought), relationship oriented and non hierarchical philosphy. 
• According to this people see themselves in coperation with others not in competition, network of personal relationships rather than isolated egos.

UTILITARIANS

• This ethic is about utilization of resources.
• Jeremy Bentham has the philosophy that said Goodness brings happiness and happiness brings pleasure.
• John Stuart Mill said that pleasures of intellect are greater than pleasures of the body.
• By inspiring these philosophies Giffort Pinchot believed that greatest good for the greatest number of people for long time.

ANTHROPOCENTRISM

• It is a human centered approach.
• It describes that humans only have intrinsic values that have only worth.
• Things are good because they are human interest.
• Animals are valuable because humans use them for various purposes for their ease.

BIOCENTRISM

• It is a life centered approach.
• Famous phrase regarding this ethic is revenge for life means to enhance life not to harm it.

ECOCENTRISM

• It is based on ecological perspective.
• This depicts that not only living organisms but also non living things such as forests, rivers, also have moral values.
