on occasion , the results of operations of our wood products business have been , and may in the future be , adversely affected if we are unable to pass cost increases through to our customers . the forest products industry in general and the wood products business in particular has been adversely affected since 2008 by the national decline in home building and the resulting weak demand and lower prices for wood products . as we experienced in 2012 , lumber demand in north america has started to improve and is expected to continue to increase due to improving housing starts and increased repair and remodel activity . 2012 form 10-k / 29 fluctuating timber prices . our results of operations and cash flows will be materially affected by the fluctuating nature of timber prices . a variety of factors affect prices for timber , including factors impacting demand , such as changes in wood products and pulpwood pricing and demand , which are affected by economic conditions , construction activity levels , interest rates , credit availability , population growth and weather conditions . all of these factors can vary by region and by timber type , such as sawlogs or pulpwood logs . timber prices are also affected by changes in timber supply at the local and national level . our timberland ownership is currently concentrated in arkansas , idaho and minnesota . in arkansas and minnesota , most timberlands are privately owned . historically , increases in timber prices have often resulted in substantial increases in harvesting on private timberlands , including lands not previously made available for commercial timber operations , causing a short-term increase in supply that has tended to moderate price increases . decreases in timber prices have often resulted in less harvesting activity , causing short-term decreases in supply that have tended to moderate price decreases . in idaho , where a greater proportion of timberland is government owned , any substantial increase in timber harvesting from government-owned lands could significantly reduce timber prices , which would harm our results of operations . for more than twenty years , environmental concerns and other factors have limited timber sales by federal agencies , which historically had been major suppliers of timber to the united states forest products industry , particularly in the west . any reversal of policy that substantially increases timber sales from government-owned land could have a material adverse effect on our results of operations and cash flows . on a local level , timber supplies can fluctuate depending upon factors such as changes in weather conditions and in the harvest strategies of local forest products industry participants , as well as occasionally high timber salvage efforts due to events such as storm damage , unusual pest infestations or fires . lumber demand in north america has started to improve and is expected to continue to increase due to improving housing starts and increased repair and remodel activity . several other factors , including demand from asia , the resource depletion caused by the mountain pine beetle , limited dealer inventories and a recovering manufacturing base , are also all contributing to higher lumber prices . the increased demand and higher prices for lumber will in turn likely have a positive effect on timber prices . in general , when pricing trends improve we increase our future harvest levels , and when pricing trends decline we decrease our harvest levels . harvest levels . changes in harvest levels on our timberlands also may have a significant impact on our results of operations . over the long term , we manage our timberlands on a sustainable yield basis to achieve a balance between timber growth and timber harvests . from time to time , however , we may choose , consistent with our environmental commitments , to harvest timber at levels above or below our estimate of sustainability for various reasons . on a short-term basis , we may adjust our timber harvest levels in response to market conditions . for example , in 2011 , in response to weak demand and low prices , we shifted a portion of our harvest from our southern region to our northern region to capture better pricing opportunities . in 2012 , due to continuing poor market conditions , we reduced the overall timber harvest from our lands to 3.6 million tons from 4.1 million tons in 2011. based on our current projections that take into consideration such factors as market conditions , the ages of our timber stands and recent timberland sales and acquisitions , we expect the overall timber harvest from our lands in 2013 to total approximately 3.8 million tons . the incremental increase over 2012 is primarily related to harvests from the new timberland acquisitions in arkansas made in 2012. we anticipate increasing our harvests to approximately 4.6 million tons annually in the next several years , as market conditions continue to improve along with increased housing starts . we also experience seasonally lower harvest activity during the winter and early spring due to weather conditions . longer term , our timber harvest levels will be affected by acquisitions of additional timberlands and sales of existing timberlands or timber deed sales . in addition to timberland acquisitions and sales , future timber harvest levels may be affected by changes in estimates of long-term sustainable yield because of silvicultural advances , natural disasters , fires and other hazards , regulatory constraints and other factors beyond our control . competition . the markets for our timber and wood products are highly competitive , and companies that have substantially greater financial resources than we do compete with us in each of our lines of business . logs and other fiber from our timberlands , as well as our wood products , are subject to competition primarily from timberland owners and wood products manufacturers in north america . demand for real estate . story_separator_special_tag revenues increased $ 27.7 million , or 6 % , in 2012 compared to 2011 , due to increased revenues from the wood products segment , partially offset by decreased revenues from the resource and real estate segments . a more detailed discussion of revenues follows in “ discussion of business segments . ” cost of goods sold . cost of goods sold increased $ 8.4 million , or 2 % , in 2012 over 2011 , primarily due to the increased cost of logs consumed , customer freight , and wages and benefits that resulted from increased production and operating hours at our wood products manufacturing facilities , partially offset by reduced logging and hauling costs from our resource segment due to the harvest deferral and lower basis of acres sold by our real estate segment . selling , general and administrative expenses . selling , general and administrative expenses increased $ 8.9 million , or 22 % , in 2012 over 2011 , primarily due to higher pension expense related to our legacy plans and increased compensation expenses and mark to market adjustments related to deferred compensation plans . environmental remediation charge . in 2011 , we recorded a pre-tax charge of $ 1.2 million to reflect increased remediation cost estimates associated with estimated liabilities related to our avery landing site in idaho . asset impairment charge . in 2012 , we recorded a $ 0.1 million charge related to write-downs of two of our real estate development projects . in 2011 , we recorded a charge of $ 1.2 million as a result of a change in the intended use of a warehouse . interest expense , net . net interest expense decreased $ 2.3 million in 2012 from 2011 due to the maturity and redemption of $ 21.7 million of debt and the lower interest rates associated with our interest rate swaps , combined with a $ 1.2 million non-cash charge in 2011 for deferred costs related to the reduction in our previous bank credit facility . 34 / potlatch corporation income tax provision . the income tax provision for 2012 was due to pre-tax income for potlatch trs . the income tax provision for 2011 was due to pre-tax income for potlatch trs and a $ 0.9 million valuation allowance related to a state net operating loss and tax credit carryforwards . discussion of business segments replace_table_token_8_th resource segment . revenues for the segment decreased $ 19.1 million , or 8 % , in 2012 from 2011 , due to our planned harvest deferral , primarily in arkansas , partially offset by higher sales prices , primarily in idaho , due to improving market conditions . total harvest volume decreased 14 % in 2012 from 2011 , accounting for a negative $ 31.2 million of the revenue variance , partially offset by a positive pricing variance of $ 12.3 million . the following table summarizes our harvest levels for the years ended december 31 : replace_table_token_9_th in our northern region , sawlog volume decreased 4 % due to the harvest deferral . sawlog prices increased 3 % as a result of strengthening demand for cedar and mixed sawlogs , partially offset by a change in product mix that contained less cedar . northern pulpwood volume decreased 17 % as a result of reduced pulpwood production in idaho in 2012 due to lower prices , and pulp and paper mill curtailments and closures in the lake states in 2012. pulpwood prices increased 4 % in 2012 over 2011 due to very low prices in the first half of 2011. in our southern region , sawlog volume decreased 33 % in 2012 from 2011 due to the harvest deferral , and prices decreased 1 % . southern pulpwood volume decreased 15 % in 2012 from 2011 due to the harvest deferral in 2012 , combined with increased production of pulpwood in 2011 resulting from pine plantation thinnings and favorable weather conditions in the latter part of 2011. pulpwood prices increased 6 % in 2012 over 2011 due to stronger demand due to decreased pine availability and a shift in product mix to higher-priced hardwoods . 2012 form 10-k / 35 expenses for the segment decreased $ 8.9 million , or 5 % , in 2012 from 2011 , primarily due to decreased logging and hauling costs and lower depletion as a result of the reduced harvest volume , partially offset by higher per-unit logging and hauling expenses , increased forest management costs due to catching up on deferred road maintenance , pre-commercial thinning and replanting , and increased commercial thinning . operating income for our resource segment decreased $ 10.2 million , or 17 % , in 2012 from 2011. real estate segment . revenues decreased $ 11.8 million , expenses decreased $ 8.5 million and operating income decreased $ 3.3 million in 2012 compared to 2011 , all primarily due to the sale of fewer acres of land in 2012. the following table summarizes our real estate sales for the years

conditions . lumber prices and volumes increased 15 % and 8 % , respectively , in 2012 over 2011. expenses for the segment increased $ 19.6 million , or 7 % , in 2012 over 2011. the cost of logs consumed , customer freight , and wages and benefits all increased as a result of increased production and operating hours . we recognized a negative $ 0.9 million charge to income related to our lumber hedge in 2012 compared to a benefit of $ 4.5 million in 2011. the wood products segment reported operating income of $ 45.5 million in 2012 compared to $ 7.3 million in 2011. year ended
