The name of the technique kind of gives it away. It's simply roots that impale the enemy. By impaling them, you can restrict their movement. An example would be having the roots impale your opponent's leg and embedding itself into the earth, making them unable to move. Not sure how you got any defensive uses out of that, but the roots won't be dense or large enough to create any sort of defense.
Dense Woodland Wall: I'm not sure where you're seeing any mention of snakes. Is that for flavor? You simply create a wall of wooden branches that interlace to form a defensive barrier after performing the handseals.
Let's continue with the next set.
(Mokuton: Yanagi) - Wood Style: Wood Willow
Type: Offensive
Rank: B
Range: Short-Long
Chakra: 20
Damage: 40
Description: User focuses his chakra and creates a huge willow tree that will sprout from the ground and attack multiple enemies with its branches.
(Mokuton: Mokujin Hitsugi) - Wood Style: Wooden Men Coffin
Type: Supplementary
Rank: B
Range: Short-Mid
Chakra: 20
Damage: N/A
Description: Creates a wooden House made form Mokujins. Best used with Wooden Men Manipulation to drain the opponent of there chakra while they fight your wooden dummies.
(Mokuton: Jubaku Eisou) Wood Release: Tree Bind Flourishing Burial
Type: Supplementary
Rank: B
Range: Short-Mid
Chakra: 20
Damage: 40
Description: The user does the Snake → Rat → Dragon → Dog → Tiger hand seals and focuses his chakra in the ground beneath the opponent. A large mayhem of branches and vines sprouts and grows, interlacing around the opponent until it forms a tree around him, restraining him completely while leaving only his head visible. With a simple push of chakra, the user can make the tree compress around the opponent completely crushing him.
(Mokuton: Mokusatsu Shibari no Jutsu) - Wood Release: Smothering Binding Technique
Type: Supplementary/Defensive
Rank: B
Range: Short-Mid
Chakra: 20
Damage: N/A
Description: The technique is similar to wood release: great forest technique in respect that the users arm transforms into several wood tendrils, which can be used to capture and restrain an enemy. The main difference is that the tendrils aren't sharp or intended to harm the target, instead spreading in a thinner manner to restricting the target as opposed to attack it. It can be large enough to trap even a large summon.
@green: Well in my defense anything can be defensive if used correctly, i.e; "the restricting part, if applied to a running ninja it halts their movement if the intent isn't to impale them :3 (given the jutsu has comma's as to show options of move series the user can use). >.<
@Blue: Yeah, the snake part was merely my lackluster attempt to describing the move ^.^

(Mokuton: Yanagi) - Wood Style: Wood Willow
This jutsu allows the user to grow out a huge tree that can attack, given its not sentient. It means the user has mental control over it. Has no handseals to boot, so by simply summoning forth wood style chakra one can seamlessly create it.
(Mokuton: Mokujin Hitsugi) - Wood Style: Wooden Men Coffin
Another follow on jutsu that allows one to create a chakra draining jutsu. How much? (I'll wait for the sensei). No handseals therefore it merely prompts the user to mold the needed chakra to create it. Using a pre-existing wood dummy.
(Mokuton: Jubaku Eisou) Wood Release: Tree Bind Flourishing Burial
Ah, yes. Finally. This jutsu has a series of handseals that enable the jutsu to be created. Very useful and actual probable to be used in combat, moreover the allows one to steam the chakra from whichever part of their body into the ground to summon roots that capture the opponent and limit their bodily movement. This coupled with funinjutsu can able interesting combinations. Interestingly, this jutsu is a Supplementary type so it cannot initiate combat.
(Mokuton: Mokusatsu Shibari no Jutsu) - Wood Release: Smothering Binding Technique
Boo-yah! This jutus is interesting and a worth-while to have. No handseals to jolt into action, merely molding one's chakra to create wood style branches that race towards their opponent and seal them in place. My other applications can be used with this jutsu.
