1. please check the writing requirement first(red words is what I added for addional information )2. im not a native speaker, so please try not to write it too professional .3. you can use the building name near the tree for naming, when you trying to mark those trees in the abstrac, you can find it at trees location picture 4. this assignment including writing and graphing.please check the instruction first thank you!

Extended Abstract Outline
Your Name
ENVS-260-section number
*Insert Title here*
Keywords:


Place between 3-6 terms here that you think the reader of the abstract might not know
off the top of their head
Definitions can come from non-scholarly sources, no Wikipedia please!
Introduction:



Necessary background information
o Ecosystem services, importance of trees
o Try and make sure these sources are relatively local to the DC area!
This is where you can tie in some of your scholarly sources. Tie in information about the
importance of trees, green space etc
Make your last sentence your hypothesis (if/then statement)
o If you need examples of hypothesis let me know!
So the experiment is to measure the carbon biomass of those trees based on the data we
collected. We have 5 people in the group, measured 30 trees totally, including DBH HIGH of the
tree,latitude and longitude.
TOOLS:
1.
2.
Methods



Well- written in paragraph format, all experimental details are covered, but not in as
much crazy detail.
Appropriate controls or replication are present and explained
Should not be longer than a short paragraph、
How to find the biomass from DBH and
height of tree species in a forest
ecosystem?
There are many methods for the carbon stock estimation and sequestration. Here, I want to know the
method/procedure to find out the carbon biomass from known DBH (diameter at breast height) and height of the tree
species in a forest ecosystem. I also want to know how to analyse these results?
Standard procedures are available for calculating volume and in turn biomass from dbh & tree
height. You may refer any standard text book on forest mensuration. It is also possible to find out
carbon biomass using standard procedures. However, what approach is most suited depends on
aspects such as the the extent of area of the ecosystem , species/ species mix and size class
distribution
Results, Data, Figures, Graphs




All figures are made correctly, with all axises labeled and a clear title.
Small caption after the chart explaining what the graph is showing. NO ANALYSIS!
Data is relevant, and contributes to the abstract
NOTE: Figures do not go towards your page count, so if you have a lot of relevant
graphs, send them all in.
Discussion




All important trends and data comparisons have been interpreted correctly and
discussed, conveying an insightful understanding of the results
Limitations of the experiment described
o Things like human error, bad weather, crazy stuff that shouldn’t have happen
Future studies based on your results
You can have outside sources here if you think it benefits your discussion!
Conclusion


A sentence or two wrapping up your paper.
Make sure this is labeled as a conclusion somehow.
o Either place it under a conclusion heading or end your abstract with “in
conclusion” or something similar.
References:


Have a references or works cited section, if you don’t your paper will be counted for
having plagiarism.
Use whatever style of citation you want except for footnotes.
NOTES:
Style


Good grammar, correct spellings
All sections are complete and show notable effort
Overall Aim


You show that you understand the lab fully
You demonstrated scientific understanding and reasonsing
At the end of each experiment this semester, you will write an extended abstract to
describe your experimental design, your results and interpretations, and connect your
research to other research in the field.
The extended abstract will include all the sections of most other scientific abstract, but
because this is the only writing you will do for this experiment, your abstract must include
more detail about your experimental designs, results, and interpretations. Additionally,
you will present figures to accompany your results and interpretations and references to
highlight the outside research you used. Your extended abstract should include, and
introduction, objective, methods, results, conclusions, key words, figures, and references
and a well-organized, detailed, and concise abstract is favored over a wordier, less
specific abstract. (Note: please do not add section headings, such as Introduction or
Methods. Instead, use your space for your writing).
