Default the low percentage of mapped reads

Hi all

I am analyzing RNA-seqs of poplar species generated by Illumia Hi-Seq with the CLC genomic workbench.
I set the minimum length fraction as 0,7 and minimum similarity fraction as 0,6, Maximum number of hits for a read as 10.
The mapped reads only take around 70% among all reads.
Is this percentage too low? Any idea to improve that? BTW, they are paired-end 100 bp reads.

Thanks!
