This Issue: Reliability of Forest Inventories and Remote Sensing (Part 2 of 3) and Some Other Good Things

RELIABILITY OF FOREST INVENTORIES AND REMOTE SENSING. (Part 2 of 3) – Recently I was doing some searching for publications on the reliability of forest inventories and remote sensing. Here are some of the sites that I found. If you know of others, please send me the information and I will post in the next NRMI. Thanks, Gyde (

FEEDBACK ON CONVERSION FACTORS – List member and retired forester Jamie Benson provided this feedback on last week’s NRMI…In the late 1970's early 1980's Canada went through the process of selecting units and calculating conversion factors for switching to metric (SI) unit. Two publications from the Canadian Forestry Service were very useful, but both are out of print and I cannot find them either at the Canadian government publications site or on line. These were: Selected metric (SI) units and conversion factors for Canadian forestry, by Murray Bowen (which is a fold out pamphlet; I have a copy), and Metric Units in Forestry, by G.M. Bonnor; I do not have a copy of this one. Both publications came out as a result of work by several Forestry Sector Working Groups of the Canadian Metric Commission, which was disbanded in about 1985 (their work was done). For the specific values requested, from the Selected values pamphlet, 1 m squared / hectare equals 4.356 00 square feet per acre; the zeros are important, since the intent was for the conversion to work both ways and to cover significant rounding errors. For the other conversion requested: 1 square foot per acre equals 0.229 568 square metres per hectare. Note the spelling of 'metre', which comes from the fact that we are using SI units, which recognizes that a metre is a measure of distance, while a meter is a measuring device (the distinction between which generated some amount of discussion during meetings of the metric forestry sectors in which I participated - I was an active member of 2 of the 5 Forestry Sector Working Groups). Other selected units are in the pamphlet, and which I could copy, but I am unsure about the copyright issues associated with just making a copy. There may be no copyright issues since all of the factors are available mathematically.

 On the question of the reliability of forest inventories, our first estimates of reliability were based on the Standard Error of the Estimate for sampling error; of course the relevance of this measure diminished as time passed since the date of survey; introducing growth factors also introduces additional sampling errors, to say nothing of other factors that reduce reliability, such as land use changes between surveys. At a certain unacceptable level of risk, it only makes sense to create a new baseline by re-doing the survey. A continuous replenishment of inventory data (xx% per year) makes financial and practical sense, especially to maintain an acceptable level of error risk, and continuity in available expertise within an organization. Thank you for this information Jamie

Latest Global Map of Irrigation Areas - The Latest Global Map of Irrigation Areas (Ver. 4.0.1) is available as a free download. The map shows the amount of area equipped for irrigation around the turn of the 20th century in percentage of the total area on a raster with a resolution of 5 minutes. The area actually irrigated was smaller, but is unknown for most countries. A special note has to be made for Australia and India where the map shows the total area actually irrigated. This is due to the fact that statistics collected in Australia and India refer to actually irrigated area as opposed to statistics with area equipped for irrigation which are collected in most other countries. An explanation of the different terminology to indicate areas under irrigation is given in the glossary. Full details at From Shaan W. IFL List.

Forests Born of Fire. Video. Western US forests burned by high-intensity fire are important and rare wildlife habitat -- but widespread policies of salvage logging and logging intended to prevent the likelihood of fire on private and public lands harms this habitat.  The video demonstrates the beauty and life found where burned forests are left to wild nature.  From MarcFink, Appeal list.

11-12 April 2013. Inventory and Data Collection: From Tactical to Strategic . Wilsonville, Oregon, USA. As inventory systems move away from intensive sampling to less intensive sampling, it becomes all the more important to maintain a reliable and quality inventory database. This session will offer a wealth of ideas and advice to keep your system on track. For more details see . From Richard Zabel, WFCA.

10-14 February 2014.Trees for Life: Accelerating the Impacts of Agroforestry, World Congress on Agroforestry. Dehli, India. Over 1000 selected participants drawn from the private sector, research and development will share the current state of knowledge and seek to accelerate the positive financial, environmental and social impacts of agroforestry. Offering a unique opportunity for the business and research communities to interact, the Congress will be built around a structure dealing with science and innovation; food and nutrition; environmental protection; enterprise; knowledge and policy environment, and climate change. It will produce a global roadmap for agroforestry in the context of world development and create a deliberate and tangible legacy in terms of recognition, partnership, investment and impact. Further information will soon be distributed on the details of the agenda and the method of registration. In the meantime, see for further details or email to register your interest.From Artur Gil, Applied GIS RS List.
