Introduction
You are a forester employed by a B.C. coastal logging company which has a sustainable approach to logging. Sustainable logging is an idea that requires that the amount harvested must not exceed the amount of wood growing. To ensure that they run their logging company in this manner a Silvicultural Plan must be developed for each area to be logged. A Silvicultural Plan in a document that explains exactly how they intend to log an area, what they intend to do to protect  the ecosystem for the multiple users, what species of trees they will replant with and how they will ensure that these trees will survive to be harvestable. By developing such a plan your company will always be assured of a sustainable supply of timber and fulfill the requirements of the leglislation to provide for multiple use of the forest resource.

Your job as a forester is to provide information about the site to be logged. This information will be used to develop the Silvicultural Plan and ensure multiple use of the resource. The information that you are required to provide relates to the process of succession. What species can we expect to grow along side of our planted trees after logging is completed, and what is the importance of these species as part of the process of sustainable logging? 
 
 
 
 
 
 



The Task
 
 

Your task is to create a page (using a web page program) that will show, with digital pictures, the succession that you think will occur after the logging has been done, and explain, using text, how each stage of the succession is important to a harvestable forest and the multiple users of the forest in the future. 

You will need to decide what climax species you intend to plant and justify this choice of species by describing the type of soil, aspect and water requirements of your site. 

You will be required to make recommendations to your employer about how you intend to protect the ecosystem (water quality, soil, wildlife and the trees).

You will also need to explain what steps you will take to provide for all the multiple users of the forest resource. (Multiple users are; forestry, agriculture, mining, fisheries, wildlife and recreation.)
 
 
 



The Process

You will work in groups of four. Each person will have a specific job.
Person 1: TECHNICIAN. This person will be responsible for assembling the word processor page for the group. 
Person 2: SEARCHER. This person will be responsible for searching the web sites and and providing information to the TECHNICIAN to put on the word processor page.
Person 3: ANALOG SEARCHER. This person will search the text and other paper references to provide information to the TECHNICIAN
Person 4: RECORD KEEPER. This person will keep track of all the efforts made by the group to complete the web quest. They should record the urls of all web sites visited and evaluate how good they were for the quest. They should also record any processes attempted and sources used. It is essential that this record be kept in as much detail as possible as it may be the only way for you to explain the problems you encountered and why you have not completed the quest.
 

Your final product will be composed of the following parts:

1. A description of the site that was logged, the species that you intend to re-plant with and the conditions that this species prefers.

2. A series of pictures that shows the succession that you predict will happen on the site with explanations next to each picture that lists the benefits of each succeeding species to the final harvestable species/ecosystem.

3. Recommendations that will explain what your logging company can do to encourage each desirable species in the succession. This section should also list the steps that should be taken to ensure that the harvestable species will be healthy and provide the best marketable product while ensuring protection for water quality, soil, and wildlife. 

4. Recommendations that will explain what your logging company will do to ensure that all multiple users have access to the resource.
 

How to complete the above four steps:

1. Use your tree book or treebook website and choose a marketable species to replant with. List the soil, aspect, water requirements, elevation and any other information needed to describe the ideal site for your chosen marketable species. Remember that these are now the specific site conditions for your succession situation and all work that follows must be based on them. 
Place a picture of this maketable species at the top of your page and list the specific conditions below the picture.

Use your green text. The pages you need are under the heading Forest Succession 

Use these links to help you:

Ecosystems

2. Locate the pictures on the T drive "welcome.htm" that will be used to create the succession. These must appear in the correct order and fit the specific site conditions from #1. You may also include invader species if you feel that they are likely to be present. Under each picture include the following information;

(i) what other species you think would grow in your specific site.
(ii) what conditions these species prefer
(iii) what benefits these species provide to the developing ecosystem
(iv) any animals associated with these succession species and list the possible benefit/harm that these may do to the developing system. Use your notes on wildlife that you took in the class and the websites provided on the handouts. You should provide an image for any of the major species with these explanations.
 

Use the copies of Pojar and McKinnon's Plants of Coastal BC and their other reference books for information on specific mosses, lichens, shrubs and pioneer species.
 

3.Using the information from #1& #2 ,list the specific steps that you would take to ensure the completion of the succession, the healthy development of your marketable species and the protection of the water quality, wildlife habitat and erosion prevention.

4.Search the web for images of the multiple users and place these on your page. Next to these images place an explanation of why you chose the image. Explain clearly what parts of the image show how you will provide for multiple user access to the resource. (Eg: We chose this image because it shows riparian zones that protect water quality for fish and recreational fishing users.)
 
 



Evaluation

Each group will be evaluated according to the following criteria. The mark will be split between all participants.

Conclusion

You have now completed your web quest of SUCCESSION and may now print/save your report to submit to your forestry company (teacher). This means that you now have a basic way to look at the forest over time and predict the the kinds of patterns that will emerge after logging. Use this information as an analysis tool whenever you are in the forest to give you an idea of the history of the area and an idea of what is likely to happen in the next decade.
